Chapter 157 LHCb Intern

Seeing that Lu Zhou hadn't written for a long time, Academician Lu asked with a smile.

"I've done the first two questions, why can't I solve the last question?"

After staring at the topic for a while, Lu Zhou raised his head and asked, "Professor, have you studied string theory?"

"What I asked you to talk about is your own opinion. Do you care if I have studied it or not?" Academician Lu said with a smile, "You can just talk about it casually, and don't care about my opinion."

Seeing that his little thoughts were seen through, Lu Zhou smiled embarrassedly, coughed lightly and said, "Then I'll just say it?"

"If you think about it, just say it directly. It doesn't matter whether you write it on paper or not." Academician Lu said.

After thinking about it, Lu Zhou decided to answer this question from two aspects.

"I don't dare to say too much if I'm not ashamed, just talk about my personal views. If it's about the development of string theory, I agree with Mr. Yang's views. Physics is a science based on experiments. A A theory that cannot be verified in experiments has only a mathematical representation, and its value is very limited."

"The core idea of ​​string theory points out that the basic unit of nature is not point-like particles such as electrons, photons, neutrinos, and quarks, but very small one-dimensional strings. And all elementary particles in nature are It is produced by the vibration of strings. But so far our understanding of matter is still at the level of microscopic particles, and no one has really seen the existence of that string. Supporting these hypotheses are only some seemingly beautiful mathematical formulas."

Academician Lu asked with a smile: "So you also think that developing string theory is useless?"

"Of course not," Lu Zhou shook his head and replied, "String theory is like a castle in the air, but it doesn't mean that the castle in the air is useless."

Academician Lu raised his eyebrows with interest: "Oh?"

"Just like the establishment of the standard model, many theories are also based on conjectures. With the advancement of technology, these theories will one day be tested. And string theory, it may just need to wait longer."

After a pause, Lu Zhou smiled and continued.

"What's more, human beings should not only have the troubles in front of us, but also poetry and distance. Aren't the research on quantum chromodynamics and even the large hadron collider in Europe built to test the Standard Model? Even if this One day we may not see it, but one day someone will see the string for us."

There was a moment of silence.

The index finger tapped lightly on the table, and after a while, Academician Lu nodded slowly.

"good."

Nice mean over?

Just in case, Lu Zhou still asked.

"Professor, have I passed these three questions?"

Academician Lu smiled and commented.

"Of course. The first two objective questions are completely correct. It can be seen that you have really worked hard in the past two months and listened to what I taught you."

Lu Zhou:? ? ?

Wait, you taught me these two months?

Without noticing the question marks on Lu Zhou's face, Academician Lu paused and continued.

"As for the last question, as I said, it is a sub-question. To discuss academic issues is to speak freely, not to follow what others say. No matter how you answer, as long as your words are reasonable, I will count you as a fault."

Lu Zhou smiled embarrassedly, and then asked: "Professor, will you take me to Switzerland?"

Academician Lu nodded with a smile: "Of course, I will prepare the relevant documents for you. You should go and deal with the visa issue as soon as possible in the next few days."

"Thank you professor!"

"You're welcome, that's what I promised you," Professor Lu smiled, paused for a moment, and continued, "By the way, I'll ask you something."

Lu Zhou asked, "What's the matter?"

Academician Lu: "The LHCb Huaguo research group still lacks a few interns. Look, are you interested in learning more?"

Hearing this sentence, Lu Zhou was stunned.

Just now he was still thinking about how to open his mouth to Academician Lu and let him sneak into LHCb to fish, but he didn't expect happiness to come so suddenly...

...

LHCb is the abbreviation of Bottom Quark Detector, and it is also an international research organization. Just like the BESlll international cooperation group named after the abbreviation of Beijing spectrometer above, it is led by one country or one organization, and scientific researchers from many countries participate to jointly complete a certain scientific research project.

At present, the focus of LHCb research is to search for the pentaquark particle "Pc+".

According to a large number of experiments and calculations, although it is not sure what this particle is, it can be known from the invariant mass spectrum analysis of J/ψp that the mass of this particle is around 4.5GeV.

However, it is a pity that the Beijing-led electron-positron collider used by the my country-led Beslll International Cooperation Group has an energy range between 1-4.5GeV, which is just stuck at the lower limit of the "Pc+" mass threshold.

To produce "Pc+", at least 6GeV of energy is required.

So unfortunately, this time Huaguo researchers can only participate in the work of the LHCb cooperation group as collaborators to find the exciting mysterious particles.

The Huaguo cooperation group is mainly in charge of Professor Gao from Shuimu University, and all major universities in China also participate. Academician Lu is also one of the heads of the Huaguo Cooperation Group, and his work is mainly to analyze the measured bottom baryon section.

Lu Zhou joined the Huaguo research team as an intern. No matter what role he played, he at least participated in this historic work.

Lu Zhou was quite excited about the fact that he was about to witness history.

Of course, what makes him more excited is that he doesn't know how much physics experience this experiment can bring him.

Anyway, this is also a moment to witness history, and it must be more exciting than the Princeton mathematics academic conference, right?

fifty thousand?

One hundred thousand?

It would be great if his physics could also be raised to LV3.

At this moment, Shi Shang's voice interrupted his delusion.

"Elbow, what are you laughing at?"

Realizing that he seemed to be laughing out loud, Lu Zhou, who was applying for a visa on the computer, covered it up with a cough: "Ahem, it's nothing, I just thought of something interesting."

Walking over and looking at the computer screen, Huang Guangming said in surprise, "Passport? Are you going abroad again?"

Lu Zhou nodded: "Yes, at the beginning of May, I will go to Switzerland with Academician Lu."

Liu Rui, who was brushing up questions, shouted: "666"

He has almost formed a conditioned reflex for the various tricks of the elbow.

Sometimes, he is also quite desperate for such a self.

Huang Guangming was shocked immediately: "Fuck, go to Europe this time to pretend to be a force? Is it still a math conference?"

Lu Zhou smiled and said low-key: "It's not mathematics, this time it's physics. And what is pretending, I just do odd jobs, mainly listening to the boss talk. Even if you want to pretend, it's not my turn." Pretend."

Huang Guangming looked disbelieving.

At this moment, Shi Shang suddenly said in an embarrassed tone, "That Brother Lu, can I ask you to do me a favor?"

"What's the matter, tell me." Lu Zhou said generously.

Shi Shang smiled embarrassedly: "Can you help me bring something back from Switzerland?"

Lu Zhou: "What?"

Shi Shang thought for a while and said, "Falman's cosmetics... seem to be called this brand."

Huang Guangming was shocked again: "Damn it, Brother Fei, do you still use cosmetics?"

"Fuck off! The one who gave you the female ticket... Well, bring it for me when you come back, and I'll convert it into soft girl coins for you."

"Okay, I'll bring it for you when I see it." Lu Zhou nodded.

It's not easy for him to do this kind of trivial matter.

But it's rare to go back to Europe once, do you want to bring some souvenirs back?

What is there in Switzerland? Swiss army knife? I don't know if I can take it on the plane...

Lu Zhou thought for a long time, but he didn't think there was anything good to buy.

After much deliberation, let's bring some milk powder to the family. Xiaotong is going to be in her third year of high school soon, and she needs to strengthen her body to prepare for the college entrance examination.

As an older brother, he can't do anything else but help her.

I forgot to ask for votes for T.T after four chapters exploded yesterday. Let's continue to explode tomorrow and start a trip to Europe~
