Chapter 763 The Answer Is Already There

The report meeting on the unified theory of strong electricity has begun.

But the audience who attended the report meeting were a little unable to sit still.

Doesn't the origin of mass necessarily come from the Higgs mechanism?

What is the interaction factor between photons and gravity?

Could the condensation of energy form mass?

Xu Chuan’s digressions and question after question before the official start of the report aroused the curiosity of countless physicists at this moment.

It seemed that the man standing on the stage already knew something.

Everyone's hearts were itching at this moment, and they wanted to rush to the stage and pull his collar to demand the answer.

But soon, the talk related to the unified theory of strong electricity attracted all their attention.

"The current unification of interactions is based on the Yang·M ills field and its extended gauge theory. For the SU (2) gauge group, the Lagrange quantity of the Yang Mills field is L =-1/4Fμv·F^μv-ψ"

"Based on supersymmetry transformations, the masses of scalar particles do not violate gauge symmetry, and their numerical values ​​cannot be determined by symmetry."

“As the baryon number density decreases, the attractive interaction between the quark pairs in the color antitriplet state increases, and the quark pairs will gradually form a true bound state, and there is also an attractive interaction between the quark pairs and the quarks with opposite colors. , forming baryons.”

On the lecture table, Xu Chuan explained the unified theory of strong electricity with reference to PPT, while writing formulas one by one with a marker on the blackboard projected through the projection equipment.

【F^i(μv)≡δμ·Av^i-δv·Aμ^i+g(f^ijk)·(Aμ^j)·(Av^k】

[dP·Γ(3)=ds*dz/z(1-z)αexp(-bΓ)*δ(1-∑n|j]

【H（Γ）dΓyf（z+）dz+】

Report to the audience.

The first row of the auditorium.

Looking at what Xu Chuan wrote on the blackboard, David Gross, the former chairman of CERN, looked at the company on the blackboard and suddenly frowned, and the pupils in his eyes unnaturally expanded a little, which was originally focused on The light on the blackboard seemed to recall a few years ago at this moment.

After a while, Gross finally came back to his senses and spoke with some emotion.

"I see. I finally understand how he bypassed the problems of quark's free asymptotic behavior to complete this work."

Sitting next to him, Witten, who was staring intently at the calculations on the blackboard and listening to Xu Chuan's explanation, looked over and asked with some confusion: "What?"

Professor David Gross did not answer the question directly, but instead said: "Do you still remember the proton radius mystery he solved at CERN seven or eight years ago and the mathematical tool he created to calculate the channel of high-energy particles?"

Hearing this question, Witten finally turned his head, looked at Gross curiously, and asked, "Of course, what's the matter?"

"No, the answer you want is right there."

Gross smiled, pointed at the reporting table, looked at the mathematical formulas written by Xu Chuan on the blackboard, and continued:

"At the beginning, I was still wondering how this calculation was done."

"Now I know that the answer was almost in our hands a few years ago."

Witten was stunned for a moment, glanced at Gross, and then at the blackboard on the reporting table, and a flash of inspiration flashed in his mind.

"You mean"

Gross smiled and nodded, and said: "Following the clue of 'the asymptotic freedom phenomenon of quarks', we successfully found the breakthrough of the soft gluon resummation effect of transverse momentum distribution. He expanded and reversed it and applied it to "On the calculation of coupling energy levels and energy eigenvalues ​​of the strong nuclear force."

"I am more familiar with this road than you are, because I have been studying it for at least four or five years."

"but."

After a slight pause, he sighed softly, and then added: "Compared with him, it seems that I am still far behind."

He was the one who originally advocated exchanging methods with Xu Chuan for mathematically calculating physical particle energy level channels as a condition for China to join CERN as a member state.

As for this theory, he has never stopped researching it, and he even thought that he had surpassed the original author in this regard.

Because he has been able to skillfully use this tool to find what he needs from the vast sea of ​​particles.

But now it seems that he is arrogant.

While he was still obsessed with how to use this mathematical tool to explore more particles in high-energy physics, that man had already applied it to a higher level.

If it weren't for this report meeting, the person standing on the stage had just given a comprehensive explanation on this aspect, and he wouldn't even have noticed these details.

David Gross is not alone in his gains.

Along with Xu Chuan's explanation, scholars who had questions about the unified theory of strong electricity began to clarify their doubts. Those unparalleled details are what every scholar cares about.

On the report stage, Xu Chuan gradually accelerated the pace of the report meeting.

The report on the unified theory of strong electricity will be more than a hundred pages long. Even if you put aside those irrelevant things, its core proof ideas and calculation processes, as well as the solutions to those branch problems, will still be at least forty or fifty pages long.

If he didn't waste some time, he might not be able to finish speaking in two hours.

After all, there are many problems in this theory, whether it is the calculation of the three most important parameters of weak-electromagnetic coupling strength, high-mass particle mass and weak-electromagnetic-strong coupling strength.

Or the influence of a single weak interaction and the joint influence of weak interaction and electromagnetic interaction, how to give a solution to find the anomaly of lepton magnetic moment, etc. These are all places where he needs to focus on explaining.

I believe that there are many people with different questions for these different key points.

If he does not focus on these places, I am afraid that the question-and-answer session will not be completed until tomorrow.

As Xu Chuan's pace gradually accelerated, the scholars in the conference hall also stared at every line of formula he wrote, even every letter, for fear of missing any details.

For those big guys sitting in the front row, there is no problem of not being able to understand these theories and explanations because of the speed increase.

At most, there is no room to exchange opinions with colleagues sitting next to them while listening to the report.

Just like Gross and Witten, there is no time to exchange mathematical tools for calculating high-energy particle channels at this moment.

As for the scholars in the middle and back rows, and the masters or doctoral students who followed their mentors to see the world, they were already confused anyway, and didn't care about the speed increase.

The pictures on the PPT scrolled by, and the formulas on the blackboard became more and more.

Completely forgetting the auditorium he was in, and the audience behind him, Xu Chuan, who was completely in the state, focused all his attention on the blackboard in front of him that had not yet been filled.

While writing on the blackboard and explaining, he was also sorting out the ideas about the grand unified theory, or the void field theory, in his mind.

Dark matter, gravitons, strong electric unified theory, standard model. One theory after another, one idea after another is constantly being harmonized.

When the PPT turned to more than 60 pages, the report meeting also came to an end.

Finally, he could breathe a sigh of relief. Professor Sheldon Glashow, who had grasped the whole proof idea, closed the notebook in his hand, looked at Professor Carlo Rubbia sitting next to him, and said with a smile:

"What an excellent theory, what do you think?"

Sheldon Glashow, the Nobel Prize winner in 1979, completed the "electroweak unification theory" with another famous professor "Steven Weinberg" and another professor Abdul Salam.

Unfortunately, he is the only one still alive today.

Professor Salam died in the last century, and Professor Weinberg, the most famous of the three, also passed away three years ago.

Sitting next to Professor Sheldon, Professor Carlo Rubbia, who was being questioned, is also a Nobel Prize winner.

If the "electroweak unification theory" was proposed by Professor Sheldon and others, then he must have a place as the biggest contributor to confirming this theory.

The discovery of W and Z field particles is inseparable from the large-scale experimental plan of him and another professor.

Hearing Professor Sheldon's question, Carlo Rubbia's eyes were fixed on the lines of formulas on the blackboard, as if he didn't hear the question, and he didn't answer for a long time.

After a long while, he replied: "It is indeed a very good theory, but I may still have some questions."

Xu Chuan's explanation did answer most of his questions, but he was not very proficient in mathematics, and he still had a lot of doubts about some of the calculations.

Carlo hoped that he could get a solution in the next question-and-answer session.

Of course, for these mathematical questions, he was still quite confident in the young scholar standing on the stage.

On the report stage, Xu Chuan, who had already pulled the last two pages of the PPT, began to put the final touches on the entire report.

".The first term corresponds to the weak interaction of the Yang·Mills field with SU (2) symmetry, the second term corresponds to the electromagnetic field, the third and fourth terms correspond to leptons and their interaction with the weak electric field, the fifth and sixth terms correspond to the interaction between the scalar field and other fields and leptons, and the seventh term is the self-interaction of the scalar field."

"Based on the symmetry breaking, the strong, weak, and electromagnetic coupling constants are unified at the Higgs mass at the 10^15GeV energy level, while the electroweak unified coupling constant is 10^12GeV, and the strong coupling constant is."

"In summary, the unification of strong nuclear force and electroweak theory has been completed mathematically!"

On the podium, Xu Chuan finished the last report with a steady voice.

The voice was not loud, but it was clearly heard by everyone.

The moment the voice fell.

In the lecture hall, everyone couldn't help but stand up. Thunderous applause broke out in an instant, in this wide and crowded auditorium.

Just like the opening of the report meeting.

This is not only an answer to the unified theory of strong electricity, but also a new starting point for physics, a cornerstone for the future, and the pinnacle of human civilization!
