"What provides the nuclear force for the nucleons is the meson acting between the nucleons, with a mass of about 200MeV. It can be estimated through calculation that only the distance term is on the order of 10 to the negative fourteenth power. The meson acting between the two protons Only by nuclear force can the electromagnetic repulsion between protons be offset and fusion reactions occur.”
It was like this for about ten minutes.
Why does the strong interaction only act over very short distances
For example, at different locations in space and time, the components of the electric field can be constructed into non-commutative operators. When constructing the Hilbert space in which these operators act, traditional particles, such as electrons, can be reinterpreted as Dirac fields. quantization.
For example, the strong interaction force is different from the weak interaction force, and there is a very typical problem...
Professor Zhang, who was standing nearby, also clapped unconsciously.
At least in his view, academic exchanges have no regard for status or honor.
Why does the strong interaction only act over very short distances
Continuing to be polite is a waste of time.
In this way, the difference between fields and particles disappears.
Continuing to be polite is a waste of time.
Students: "..."
Staring at the simple calculations on the blackboard, Lu Zhou suddenly spoke as if talking to himself.
Can we use a concise mathematical form, like the Weinberg-Salam-Glashow electroweak unified theory, which describes the electromagnetic force and the weak interaction force in a unified way, to describe the strong interaction, and combine it with the electromagnetic force? Reach unity
After writing this, Lu Zhou stopped writing the chalk in his hand, looked back at the students in the lecture theater who were either confused or listening seriously, and said with a smile.
When he was at Princeton, he often asked his students to speak for him.
[…]
Of course, it's not easy to do this.
Answering this question cannot solve the miniaturization of controllable fusion, nor can it bring any degree of innovation to the existing controllable fusion technology. However, Lu Zhou’s intuition tells him that if this problem can be solved theoretically, it may be possible to solve the problem. This question provides a clue, or idea...
If that's the case, that would be terrible...
After walking to the blackboard and standing still, Lu Zhou picked up a piece of chalk.
“How do you explain the existence of a mass gap in mathematical language?”
According to the viewpoints of quantum field theory and quantum chromodynamics, the four fundamental forces and traditional particles can be unified.
Of course, it's not easy to do this.
[V(q)=-g square/(|q| square+mφ square)]
Without making any pause, Lu Zhou, after finishing his sentence, turned back to the blackboard again and spoke lightly.
"Don't be so polite, I just happen to have some ideas."
"Do an inverse Fourier transform on it!"
According to the viewpoints of quantum field theory and quantum chromodynamics, the four fundamental forces and traditional particles can be unified.

The answer is obvious…
It is also recognized by the international mathematics community as one of the seven millennium problems...
When he was at Princeton, he often asked his students to speak for him.
It's not that he doesn't understand, it's that he really can't believe that someone can deduce these things on the spot in such a short period of time.
Zhang Zhongqing, who was standing nearby and watching, also looked confused.
The bell rang for the end of get out of class, and Lu Zhou still stood there motionless, seeming to be thinking about something.
"Professor Lu, please." Professor Zhang immediately made a gesture of invitation and respectfully gave up the podium.
It’s unbelievable that these were all completed on the spot in less than ten minutes…
In this way, the difference between fields and particles disappears.
Continuing to be polite is a waste of time.
Seeing that Lu Zhou didn't respond, Zhang Zhongqing couldn't announce the end of get out of class without permission, let alone disturb his train of thought.
Meanwhile, on the podium.
"This kind of problem cannot be solved by undergraduates. In addition to a deep understanding of quantum chromodynamics, it also requires a deep mastery of functional analysis."
It is also recognized by the international mathematics community as one of the seven millennium problems...
Applause started from the first row.
Can we use a concise mathematical form, like the Weinberg-Salam-Glashow electroweak unified theory, which describes the electromagnetic force and the weak interaction force in a unified way, to describe the strong interaction, and combine it with the electromagnetic force? Reach unity
It was like this for about ten minutes.

"Don't be so polite, I just happen to have some ideas."
Like waves crashing on the shore, spreading to the back row.

Lu Zhou stopped writing the chalk in his hand, looked at the calculations on the blackboard, and spoke slowly.
“How do you explain the existence of a mass gap in mathematical language?”
For the previous simple problem, the calculation is over at this point.
The classroom itself is also one of the places for academic exchanges.
Hearing this question, Zhang Zhongqing was stunned for a moment subconsciously, then his face turned red, and he hesitated for a while like a student.
"This kind of problem cannot be solved by undergraduates. In addition to a deep understanding of quantum chromodynamics, it also requires a deep mastery of functional analysis."
At this moment, Lu Zhou didn't notice their expressions, he was completely immersed in his own world.
MMP!
"...I really don't know how to do this."

Staring at the simple calculations on the blackboard, Lu Zhou suddenly spoke as if talking to himself.
However, the problem he was thinking about was not just this.
According to the viewpoints of quantum field theory and quantum chromodynamics, the four fundamental forces and traditional particles can be unified.
"The above are relatively simple, but some skills will be used in the next step."
After a two-second pause, Lu Zhou continued, "However, it's actually not as complicated as everyone thinks."
[…]
"I didn't ask you, you definitely wouldn't..."
Seeing that Lu Zhou didn't respond, Zhang Zhongqing couldn't announce the end of get out of class without permission, let alone disturb his train of thought.
When he thought that this big boss actually sat in his classroom and listened to the class for so long, he felt really surprised and happy at the moment, as if he had won the lottery. I was surprised that I didn’t notice it at all, but I was happy that I could brag with others when I went out. We were also people who had taken lessons from Nobel Prize-winning experts.
The swishing sound of chalk rubbing against the blackboard became faster and faster, and the expression of Zhang Zhongqing standing next to him became more and more shocked. As for the students in the audience, they looked at the blackboard blankly. Even the top students who had already flipped through the textbooks in advance looked at a loss when faced with the complicated calculation process.

Lu Zhou muttered to himself, leaving a blackboard filled with calculations. Lu Zhou turned around and left the classroom, leaving behind a stunned professor and students.
But for him, he saw a simpler way to solve the nuclear force distance... at least much simpler than the two ones he remembered.
"Don't be so polite, I just happen to have some ideas."
The bell rang for the end of get out of class, and Lu Zhou still stood there motionless, seeming to be thinking about something.
No one could answer him.

"...I really don't know how to do this."
"Electromagnetic interaction exchanges photons, and the mass of photons is zero, so for electromagnetic interaction, V is proportional to 1/r."
[V(r)=-g squared/4πr·e^(-mφr)]
After all, this is currently one of the most difficult propositions about a unified field theory in particle physics.
Like waves crashing on the shore, spreading to the back row.
However, the problem he was thinking about was not just this.

After speaking, Lu Zhou printed the chalk in his hand on the blackboard and calculated while writing on the blackboard.
