At the same time, on the other side of the Eurasian continent, Lecture Hall 1 at CERN's headquarters in Switzerland is a crowded scene.

Luo Wenxuan, dressed in formal clothes, stood in the aisle next to the podium, carefully checking the paper manuscript in his hand, while constantly taking deep breaths in order to adjust his beating heart.

Although it is not the first time to stand in this place, the feeling of standing under the stage and standing on the stage is completely different.

It is the temple of the international physics community.

In half an hour, he will be tested by the world's top scholars in physics.

Just as Luo Wenxuan was nervously making the final preparations, a familiar voice suddenly came from the side.

"Your tie is too tight, and it will affect your ventilation."

As soon as he heard this voice, Luo Wenxuan immediately looked back, and a surprised expression appeared on his face.

"Professor?"

"It's not so surprising, you should know that I've been with CERN for at least six months of the year," Witten smiled and joked in a witty tone, "What's more, there's such an important report waiting for me." ”

Luo Wenxuan smiled embarrassedly, reached out and scratched the back of his head.

"I'm thankful I didn't mess up."

"Since Professor Lu has chosen to entrust this report to you, it means that he believes that you can do it. If it were you, there would be no need to be so nervous, just an ordinary report meeting. ”

Nonsense...... You're a Filipino Award boss, so you don't need to be nervous, but the problem is that I haven't won a Fields Medal.

Luo Wenxuan didn't speak, and complained in his heart speechlessly.

Seeing that he didn't speak, Witten paused for a moment and continued, "Speaking of which, Professor Lu, is he okay?" ”

Luo Wenxuan: "It's good in every sense, but I'm still as busy as ever in research. ”

"Really? It's quite his style," Witten smiled, "Actually, I don't think there's any need for him to be in such a hurry, he's already reached heights in just a few years that many people can't reach in their lifetimes, and he still has decades to continue to study in the future...... My suggestion is that he could consider a healthier lifestyle and take time off from his studies to travel or something. ”

Luo Wenxuan: "I will convey your suggestion to him." ”

"I can't talk about suggestions, it's just a little bit of my own understanding of my past life," looking at Luo Wenxuan, whose expression was still very nervous, Witten smiled and said, "And you, take it easy." If I'm not mistaken, this isn't your first time here. ”

Luo Wenxuan said nervously: "But I have always been offstage before. ”

Wei Teng smiled and said, "Aren't you going to stand on the stage soon?" I'm optimistic about you, don't let me down. ”

As he spoke, he patted the former student on the shoulder, turned and walked away in the direction of the banquet.

……

After chatting with his former mentor for a few words, Luo Wenxuan felt that his originally nervous mood relaxed a lot.

Soon, it was time for the presentation to begin.

Walking to the front of the stage and standing still, Luo Wenxuan took out his mobile phone from his pocket, dialed the Internet phone, and put it next to the microphone on the multimedia lectern.

Facing the gradually quiet venue, he cleared his throat and spoke.

"Due to various reasons, Professor Lu was unable to come to the site in person, so I was appointed to conduct this lecture on his behalf. If you have any questions about this, you can raise them before the presentation. ”

As soon as the words fell, someone raised their hand.

Luo Wenxuan made a gesture of please and said politely.

"Professor, please."

Standing up from the seat tremblingly, I saw an old man with a hooked nose and a furrow on his face, staring sharply at Luo Wenxuan standing on the stage, and said slowly in an unhurried but weighty tone.

"There is only one question I want to ask, what is your role in the study of the Young Mills equation problem?"

Luo Wenxuan observed the other listeners, and it seemed that many of them were concerned about this issue.

Adjusting his breathing, he said in as smooth a voice as possible.

"I ...... The main thing is to provide a possible proof idea, and to discuss the way to solve the problem. Of course, as stated at the end of the paper, he did the main argument alone. ”

The old man continued, "Can I think that your point of view represents his?" ”

Didn't you say that you should only ask one question?

Complaining in his heart, Luo Wenxuan continued.

"Absolutely...... Unless Professor Lu expresses his clear objection," he said, pointing to the mobile phone on the multimedia lectern and continuing, "He will be online throughout the presentation, and if I have anything immature, he will add ...... If he interrupts me, his statement will prevail. ”

The old man nodded and sat back.

Luo Wenxuan breathed a sigh of relief.

"Then I, please turn the paper in your hand to the abstract part, and let's start from the beginning......"

Although it is impossible not to be nervous, he quickly got into the groove after the briefing began.

In fact, he has not had the experience of giving reports at CERN, and even under the cultivation of Witten, he has had many opportunities to give reports on stage, but those reports are not particularly important, and there are not so many bigwigs in the audience.

Minutes and seconds passed.

In the blink of an eye, an hour has passed.

Finally, seeing that the PPT turned to the last page, Luo Wenxuan finally breathed a sigh of relief, but there was no feeling of taking it lightly in his heart.

Although the PPT is finished, the report will not end.

The next question session is the key to the whole report!

"That's basically all for the details of this paper...... If you have any doubts, you can ask them. ”

Seeing that he announced that he had entered the question session, the hands of the audience immediately raised.

Luo Wenxuan glanced at the old man who raised his hand, and saw that it was still the one from before, so he nodded to him.

"Please."

Trembling and standing up from his chair, the hook-nosed old man asked in a steady voice.

"On page 9, line 23 of the paper, for a more generalized polynomial interaction of the shape λR(φ)+φ² on R², where there is a lower bound at R(φ), and 0<λ<λ0 "1, how do you know its existence and isolated single particle spectrum?"

After hearing this question, Luo Wenxuan breathed a sigh of relief.

The difficulty is decent, and it's not a particularly tricky problem.

Clearing his throat, he walked over to the whiteboard, picked up his marker and replied as he took the board.

"For R(φ) of a two-dimensional small coupling constant, the occurrence of bound states depends on the specific situation of R(φ), and a field theory with bound states will have a mass operator M, whose spectrum has a mass gap (0,m) and an upper gap (m,mb)...... Therefore, we can know that its existence is known. ”

"As for the ...... of single-event spectra"

As soon as he was halfway through his words, the marker in Luo Wenxuan's hand suddenly stopped, and along with his voice, it was also stuck there.

It was as if a lump of cotton was blocking his throat, so that he couldn't make a sound.

Isolated single-particle spectra......

MMP！

How to answer this?

A drop of cold sweat gradually slipped down his forehead.

The speed of his brain was at its limit, and he called on almost all of his brain cells to think about it.

However, it was in vain.

Whispers gradually spread in the venue, and from the eyes of several professors sitting in the front row, Luo Wenxuan saw a trace of disappointment.

Swallowing a mouthful of spit, he gradually felt a chill in his hands and feet.

What to do......

He couldn't imagine what he would have done if he messed up.

Even if Lu Zhou might forgive him without much care, he couldn't forgive himself.

However, at this moment, a voice like heaven sounded from the mobile phone resting on the multimedia lectern. Although it was only four words, it filled him with strength in an instant.

Lu Zhou, who only listened to the other end of the phone, said in an understated but extremely reliable voice.

"I read, you write."
