The heated discussion about W boson mass being overweight gradually disappeared after about a month.
Of course, the physics community is also aware that everyone is now waiting for the latest results of CERN and Institute of High Energy Physics. In addition, CERN has also discussed at the meeting and finally decided to put the verification of W boson mass as a top priority in the new collision mission in three months.
This all takes some time.
Scholars in related fields have also returned their attention to their own research.
Time has come to September 1st.
It's the entrance season for a new year, and the high school students who just completed the college entrance examination in the first half of the year are now promoted to college students.
In addition, the same is true for graduate students who have finally successfully entered the school of their choice after passing the preliminary examination and re-examination.
Chinese Academy of Sciences, Basic Science Academy.
Graduate students Mathematics Research Institute and Institute of Physics next door have today entered the place where they will live as graduate students.
This kind of research institution generally opens graduate programs, which are suitable for students who are more interested in research. Compared with postgraduate studies at universities, they are more professional and pure.
At this time, Mathematics Research Institute is in the office of Academician Xun Yong.
This year he also admitted two master's students and one doctoral student.
At this time, his two new master's students, who had just entered school today, were reporting to his tutor in the office.
"Hello, Teacher Xun!"
"Teacher Xun!"
The two newly admitted master's students were very excited. After all, who would have thought that they would successfully become the disciple of an academician.
In particular, this academician is a genius. He was elected as an academician at the age of 42, making him the youngest among all academicians.
"Hello."
Looking at the two young people in front of him, Xun Yong smiled and nodded, "Gong Weihua, and Zou Qiao, right?"
"Yes." The two nodded.
"Okay, then, Gong Weihua, Mathematics Department graduated from the University of Science and Technology, right? I remember during the previous interview, you said you wanted to study Algebraic Geometry? Then during the undergraduate period I also posted an article about Core Journal, but this paper is not about Algebraic Geometry, but about Complex Analysis. Why are you interested in Algebraic Geometry now?"
Gong Weihua scratched his head and said sheepishly, "Yes, I just want to be a graduate student. I should also study some more in-depth mathematics."
Xun Yong smiled and said, "Okay, if Complex Analysis has a good foundation, it will be very helpful for learning Algebraic Geometry. You can try it first. Have you learned GTM52?"
Gong Weihua said, "After I learned it and decided to get here as a graduate student, I started to study GTM52 by myself, and I have finished reading it now."
"Yeah, pretty good."
Xun Yong nodded with satisfaction. From this point, it can be seen that Gong Weihua has a plan for his graduate career. He has set Algebraic Geometry as his goal very early. As a teacher, I like students like this the most.
"The Algebraic Geometry class here is taught by Professor Zhang Ping. You can listen carefully when the time comes. His class is very good. Then GTM52 should be studied carefully. It is best to study it several times., In addition, you must also study Abstract Algebra and Algebraic Topology. If you want to learn Algebraic Geometry well, you must master these prerequisite knowledge."
"Thank you, teacher." Gong Weihua nodded.
"Yes." Xun Yong nodded, then turned to look at Zou Qiao next to him, and began to ask about his future plans.
Zou Qiao is a graduate of Qinghua University, and his performance during his undergraduate period was even more outstanding. He not only published a core article, but also published an SCI article in the second area. It can be said that even studying abroad is more than enough, but in the end he chose to stay in China, perhaps because the tuition fees abroad were too expensive.
In this way, after another exchange, Xun Yong also learned about the direction Zou Qiao planned to research.
"Analytical mathematics is not bad. Let me take a look at your transcript... Well, during my undergraduate studies, I got full marks for Real Analysis and complex analysis. Functional Analysis also got a 99, which is okay. There are also harmonic analysis, Nonlinear Analysis..."
Analytical mathematics is also a good direction, and it is also very useful. It can be used to study problems in many fields of mathematics. Even if you want to change careers in the future, the foundation of analytical mathematics can provide a lot of help.
In this way, Xun Yong gave his two new disciples good guidance on the future direction, and then assigned them short-term tasks and long-term tasks. The short-term tasks were the goals of learning, and the long-term tasks naturally referred to their graduation thesis.
Mathematics graduation thesis is probably one of the most difficult majors, so they have to be well prepared for whatever they want to write.
"... Okay, if you have any other questions, you can talk to your senior brothers. They should know more than me. The laboratory is next door. I will take you to get to know it later."
"Okay, teacher." The two nodded.
At this time, Zou Qiao asked again, "By the way, teacher, is there another senior fellow with a doctorate who enrolled in school with us? Why haven't we seen him?"
"He."
Mentioning this fellow doctor, Xun Yong had a slightly strange expression. "Maybe he is busy and has no time to come over."
"Huh?"
Gong Weihua and Zou Qiao were immediately confused, what the hell?
Is their doctorate brother so awesome?
He didn't come on the first day of registration, and their academician wasn't angry?
At this moment, the office door was opened, and a voice came in. "Teacher Xun, look what you said, I still have to come here on this first day."
Xun Yong saw this person and said to the two people in front of him, "Here, your doctor brother is here."
The two people turned their heads in confusion, and then they were both shocked.
"Xiao Xiao Xiao Xiao...Scholar Xiao?!"
"Fuck!"
This doctoral student of Xun Yong is none other than Xiao Yi.
Last week, Academician Xi Lan came to Xiao Yi and told him that it was time to choose a mentor.
Other graduate students had chosen their supervisors a few months ago, but Xiao Yi had not yet decided because of his special circumstances.
It is precisely because of this that Gong Weihua and Zou Qiao did not know that there was another doctoral fellow who was enrolled with them. They only learned about this news two days ago when Xun Yong accidentally revealed that he had used up the quota for one doctoral student and two master's students this year.
Xiao Yi confirmed his mentor a few days ago.
For him, any academician in Mathematics Research Institute can be his mentor, and Xun Yong has accompanied him to the United States, and the communication between them is relatively harmonious, so it is normal to choose him.
"Junior Brother Gong and Junior Brother Zou, right? Nice to meet you."
Xiao Yi said hello to the two junior brothers.
Looking at the face of Xiao Yi that they had worshiped countless times in various places, it took the two of them a long time to recover from the shock, and then hurriedly responded, "Xiao... Hello, Senior Brother Xiao."
Xiao Yi smiled and nodded, then he looked at Xun Yong and said, "Mr. Xun, were you making plans for them just now?"
"Yes." Xun Yong nodded. "Why do you want me to make some plans for you?"
Xiao Yi chuckled, "You are the teacher now, you have the final say."
"Let's go." Xun Yong immediately rolled his eyes. "You graduate earlier, and I will be relieved earlier. Being your mentor is too stressful."
"However, I still have to ask, what do you plan to write for your graduation thesis?"
"Well..." Xiao Yi thought for a moment and finally shook his head, "I haven't decided yet."
Xun Yong waved his hand. "Anyway, just don't give me the whole Millennium Prize Problems when the time comes, otherwise it will be too uncomfortable for me as a tutor."
"Uh... I'll try my best."
Xiao Yi's expression is a little strange.
Isn't the mass gap problem he recently studied Millennium Prize Problems?
Xun Yong didn't notice Xiao Yi's strange expression and said, "Okay, I will take you to the laboratory to meet other people now."
Then he got up and took the three people to the laboratory next door.
The math laboratory is just a simple work station with nothing.
The laboratory is quite big, because there are not only students from Xun Yong, but also other students. He is considered a senior tutor, and there are students from other junior tutors in the laboratory.
As for research groups like those in other professional laboratories, there are none here.
After all, they are not engaged in any project, and the teacher does not think that his students can help with his project.
Therefore, they basically don't even have group meetings. At most, the instructor feels that it's time to put some pressure on his students, so he will hold a group meeting and let them talk about what they have done during this time.
It can only be said that basic mathematics is like this. What you have to do every day is to get up, eat, read papers, write papers, and sleep. It is completely free-range. However, other majors have a lot to consider. Not only do you have to read papers and write papers, but you also have to do projects. You may even be exploited like a cow or a horse.
"Hey, aren't half of you here?"
After walking into the laboratory and looking at the people inside, Xun Yong frowned and asked, "Hu Chengbo, what's going on?"
Hu Chengbo is his eldest disciple. He has been studying for a doctorate for almost 4 years and may not be far away from graduation.
Hearing the teacher's question, Hu Chengbo didn't know how to answer for a while, "Uh... well..."
Who would have thought that their teacher would come over to check attendance today?
It seems like it hasn't happened before?
"Forget it, I'm too lazy to ask you." Xun Yong shook his head and could guess what was going on.
It's just that he might still be sleeping in the dormitory, playing games, or he might have run out to play.
"Okay, everyone, please pay attention. Let me introduce you to your new classmates this year."
Standing in front of the laboratory, Xun Yong clapped his hands.
Soon the graduate students in the laboratory looked over curiously and glanced at the three students standing next to Xun Yong.
After a brief glance, their eyes suddenly widened when they saw Xiao Yi among them.
"I'm super, Scholar Xiao?"
It can only be said that the reactions of Gong Weihua and Zou Qiao are exactly the same.
Xiao Yi actually became their classmate?
Xiao Yi smiled and nodded to them and said hello, "Hello everyone."
Xun Yong said, "I won't introduce Xiao Yi. You may know him better than I do. Well, Xiao Yi will probably be your classmate for only one year. You should hurry up and build a good relationship with them during this year. This is the opportunity that I, your teacher, have won for you."
Hearing this, Xiao Yi couldn't laugh or cry, and the graduate students in the laboratory immediately clapped their hands excitedly.
Xiao Yi In the eyes of young people like them, that is an absolute idol, and now they can actually study with their idol?
Hmm... well, there is still a question whether Xiao Yi can take classes with them.
After introducing Xiao Yi, Xun Yong introduced Gong Weihua and Zou Qiao to them.
"Hu Chengbo, these are your junior brothers, please make arrangements for them."
Xun Yong left the laboratory after finishing speaking.
And Hu Chengbo nodded, and then he stepped forward and said, "Senior Brother Xiao, please come here, and Junior Brother Gong and Junior Brother Zou."
Xiao Yi said quickly, "No, no, no, Teacher Xun just said, you are the senior brother."
"You are embarrassing me. Whoever graduates first is the senior brother. You will graduate in one year. I haven't even figured out the topic for my graduation thesis yet. You are the senior brother!"
Hu Chengbo waved his hand quickly.
Xiao Yi couldn't laugh or cry, and finally said, "Forget it, Senior Brother Hu, I won't argue with you. Why don't we add WeChat first? By the way, what is your name? I didn't hear clearly what Teacher Xun said just now."
When he heard that Xiao Yi could be added to WeChat, Hu Chengbo's eyes lit up and he immediately took out his phone. "Okay, okay, add it now, my name is Hu Chengbo."
"Hu Chengbo..." Xiao Yi was suddenly startled, "Cheng Bo?"
He almost didn't stop and started coughing.
Hu Chengbo's eyes turned resentful.
"Hahahaha!"
Everyone else in the laboratory burst out laughing, including Gong Weihua and Zou Qiao next to them.
"Sorry, sorry, that, I didn't mean to."
Realizing that this was a bit bad, Xiao Yi quickly apologized.
Hu Chengbo waved his hand. "It's okay, I'm used to it."
Then he glared at the other people in the laboratory. "You guys are just laughing so hard, why don't you come up and ask for WeChat?"
After hearing what this senior brother said, other people reacted one after another, and then quickly came forward and added Xiao Yi to each other on WeChat.
In this way, Xiao Yi quickly got into a fight with them.
Of course, Gong Weihua and Zou Qiao quickly integrated into it, even easier than Xiao Yi.
After all, although Xiao Yi is the same age as them, and he is even the youngest. The others are already in their twenties, and Xiao Yi is only eighteen years old, but in the eyes of others, Xiao Yi is always a mathematician who has been famous in the mathematics world for a long time.
There is still a sense of distance.
Of course, Xiao Yi didn't care about this sense of distance.
After all, as Xun Yong said, he will only stay here for a year at most.
There is a chance that he will just be a passerby in this laboratory.
Time flew by again, and it was a day in mid-October.
In the dormitory of Xiao Yi, he was sitting at his desk, continuing to think about the quality gap issue.
The desk is filled with all kinds of scratch paper, and the ground and the trash can next to it are filled with a lot of crumpled paper.
These drafts are filled with his thoughts and research on this issue from various angles.
But what I have to admit is that Millennium Prize Problems is indeed Millennium Prize Problems.
It was much more difficult than any problem he had ever studied.
Especially this question, it almost accommodates top mathematics problems and top physics problems together.
To solve this problem, it is basically impossible if we cannot achieve two blooms in these two fields.
"Initially, I thought about it from the perspective of Lattice QCD. By discretizing space and time, I verified the existence of the mass gap through numerical simulation... However, although the numerical simulation provided a lot of evidence, this evidence did not constitute a strict mathematical proof and could only be said to be a auxiliary verification."
"Then I tried the Schwinger-Dyson equation. By analyzing these equations, if I could find a non-zero solution to the self-energy function of gluons, this would indirectly prove the existence of the mass gap. However, although some solutions were found, these solutions were too complicated and could not be directly converted into mathematical proofs."
"Then there is the renormalization group method, which analyzes the behavior of Yang-Mills theory under different energy scales... This is a good direction. The renormalization group flow shows a non-perturbative fixed point, suggesting that there may be a mass gap. Unfortunately... this thing may be harder than finding the analytical solution of NS equation."
Xiao Yi sighed.
"Then there is also the use of AdS/CFT duality to understand the non-perturbative properties of Yang-Mills theory through the dual relationship between conformal field theory and Anti-de Sitter space, but again, this is too complicated."
He knocked on his head. The above four points were the four angles he had tried during this period, but although they had made breakthroughs, they all completely stuck him at a certain point.
"Probably, only by upgrading the BUFF to level 5 can I have a chance to solve these problems that are blocking me, right?"
He shook his head helplessly.
At this moment, there was a knock on the dormitory door.
He opened the door in confusion, and then saw Academician Pang Cheng from Institute of Physics walking in, followed by several people from the research team.
"Teacher Pang, and Senior Brother Xu, Junior Brother Cai? Why are you here?"
He has now changed his name to Teacher Pang Cheng because he is now a doctoral student of Institute of Physics. After all, it was Institute of Mathematics and Institute of Physics who agreed to let him become a graduate student of these two institutes at the same time.
And Pang Cheng is his Ph. D. supervisor in physics.
When Institute of High Energy Physics academician Tang Yifang learned about it at that time, he even complained that he did not tell him such a big thing earlier and actually did not choose them Institute of High Energy Physics.
Xiao Yi has no choice. After all, his current dormitory is so close to both Institute of Physics and Institute of Mathematics, so of course it is more convenient for this doctor of physics to live in Institute of Physics.
Pang Cheng smiled and said, "Of course there is good news. Our project has been completed and it has been submitted to "nature". We can wait for the good news."
"Oh!" Xiao Yi raised his eyebrows. "It is indeed good news."
After all, he is also one of the co-authors on this subject.
Pang Cheng did not win a single work, but was the corresponding author.
At this moment, there was another knock on the door.
As a result, I saw academician Xi Lan coming.
When he saw Pang Cheng, he immediately stared. "Pang Cheng, what are you doing here?"
Pang Cheng narrowed his eyes and said, "Don't you know that I am Xiao Yi's tutor? Isn't it normal for me to come to my student?"
Xi Lan's fists suddenly tightened.
With a cold snort, he pushed Pang Cheng aside, then smiled at Xiao Yi again and said, "Xiao Yi, I'm here to give you something."
Then, he took out an envelope and handed it to Xiao Yi, "Open it and take a look."
Xiao Yi took the envelope in confusion, opened it, and was stunned.
"National Science and Technology Awards Conference invitation?"
