Chapter 232: bad news

The shorter the word, the greater the amount of information.
Thinking of what Academician Lu said to himself after returning from the International Conference on Theoretical Physics in Brussels, Lu Zhou had a vague feeling that Professor Frank might have something important to say to himself.
So he didn't hesitate and quickly responded to the email.
I can do it anytime, when will you be free?
After a while, Professor Frank did not reply.
Lu Zhou glanced at the time. It is estimated that he fell asleep, then got up, went into the bathroom, took a shower, and went to rest.
No words overnight.
In the early morning of the next morning, Lu Zhou got up while listening to the alarm, checked his e-mail box, and received a reply.
The day after tomorrow I will go to Shixi University, where I will stay for about three days. We can meet there if you are free.
Lu Zhou glanced at the calendar.
There was a lecture two days later, but he had already asked for leave from Professor Deligne.
After thinking about it, he edited an email and replied.
OK, then at noon the day after tomorrow, I will contact you when it arrives.
The reply was only two letters.
ok
...
Located on the west coast of New York, it is the economic and cultural hub of the entire west coast, and it is also one of the technology centers on the west coast.
Many people know Wall Street and Broadway on Manhattan Island, but few people know that it is on Long Island next door, and also located at Brookhaven National Laboratory, one of the world's top comprehensive scientific research bases.
There have been many Nobel Prizes here, including the parity of Yang Zhengui and Li Zhengdao, and the j particles found in Ding Zhao. Currently there are about 3,000 researchers and engineers here, and an average of more than 4,000 visiting scholars work with this each year.
Although not comparable to cern, it is also a considerable number.
To a large extent, the meaning of the collider is here. The discovery of a novel particle on the surface does not seem to change human life immediately, but it can attract a large number of scholars to gather here, spawn a large number of suppliers focused on cutting-edge equipment, and form a huge "research ecology" .
For example, the storage ring of the hadron collider requires nearly harsh vacuum conditions, which has led to the development of ultra-high vacuum technologies, and these technologies have finally exerted industrial value in the medical and electronics industries.
And there are many similar things.
The laboratory is currently part of the Department of Energy, but is managed by the Brookhaven Institute of Science, a company established by Stony Brook University and the Battle Institute.
It happened on Monday that Lu Zhou arrived in New York with his newly bought car.
Professor Frank and he made an appointment to meet at the cafe in front of Stony Brook University. I don't know if it is Lu Zhou's illusion. I always think that the professors he knows have a soft spot for things like coffee.
Sitting at twelve o'clock in the cafe, Professor Frank arrived at the meeting place on time, and was carrying his laptop.
"Sorry, I had a delay in the meeting and kept you waiting."
Lu Zhou smiled and said, "No, I just arrived."
Sitting opposite Lu Zhou, Professor Frank saw the waiter and said easily: "Give me a cup of American coffee and a tuna sandwich."
Waiter: "Do you need sugar?"
"No need to."
While ordering from the waiter, Professor Frank put the laptop on the table, opened the folder, looked at Lu Zhou and asked, "You brought a USB flash drive."
Lu Zhou nodded, took the USB flash drive out of his pocket and put it on the table. "Take it ... can you tell me what the is going on? Although I don't mind drinking coffee with you, but if it only depends on the data, Why don't we use email as usual? "
Professor Frank did not answer this question immediately, but operated the computer, opened a chart file, then turned the laptop to the side and presented it to Lu Zhou.
Looking at the image on the screen, Lu Zhou frowned slightly. "This is it?"
Professor Frank moved the chair to the side of the table, the image on this screen said.
"This is the latest experimental record of cern. The two charts above are the distribution curve and statistical chart of collision cases in various energy regions collected by the cms detector. You should be able to see the meaning of this chart."
Staring at the image for a while, Lu Zhou's expression gradually dignified, "Confidence has dropped?"
Professor Frank sighed softly, "Yes, no matter how many groups of experiments we repeat, the confidence level still does not reach the 3sigma standard. And at the end of last year's experiment, it appeared in the characteristic peak of the 750gev energy region, and even contracted ... That's what you see as a drop in confidence. "
Staring at the icon for a long time, Lu Zhou did not speak for a long time.
He had vaguely guessed why Professor Frank wanted to talk to him in person.
Seeing Lu Zhou didn't speak, Professor Frank paused for a moment and continued.
"The international conference on theoretical physics in Brussels at the end of the year was very large. It was a pity that you missed that conference."
"The latest discovery on the report accelerator at that time was the newly elected 16th Chairman of the Cern Board, Ms. Fabio Lagianotti. The scene of the report was full, and many people sat on the ground, even outside corridor."
"That report covered a lot of things, especially 20 full minutes, and reported the discovery of cern on 750gev."
"You should be able to understand these pictures, or you can bring them back to study," said Professor Frank, sighing, and said softly, "though the meaning is no longer significant."
Lu Zhou did not look at the computer anymore, but stared at Professor Frank, waiting for him to continue.
In response to the junior's sight, Professor Frank shrugged his shoulders, trying to make his tone not so heavy, and continued: "However, you have been a big help. From May last year to two months ago A large number of papers have emerged on arxiv, many of which are novel physical models. They are not necessarily correct, but they are very useful. And the two papers we have collaborated on have been cited many times by colleagues. "
Although this sentence sounded like comfort, Lu Zhou did not get any sense of comfort from it.
For this subject, he has spent half a year ~ EbookFREE.me ~ Although for a theoretical physicist, half a year ’s time is not much, and it is not even enough for them to grow their hair out again, but For Lu Zhou, the meaning of this topic is completely different.
Not only because of the models he built out of those busy times, but also because of the hope he poured into 750gev ...
Taking a deep breath, Lu Zhou looked at Professor Frank and said slowly, "What do you mean?"
Professor Frank's response confirmed his guess.
I saw the old man stood up, took off his hat, nodded slightly, and expressed his gratitude,
"Cern's official explanation to the experts of the member states is still promising, but it is clear that from the experimental plan after January 1, there will no longer be experiments to retrieve the anomalous 750gev characteristic peak, because it is disappearing, and Every collision of the particle group is burning money. It is a pleasure to work with you, and I sincerely thank you for your work, but ... "
As a result, Professor Frank cleared his throat, lowered his eyes slightly, and expressed regret. "The reason tells us that it is easier to build a physical model to explain why there is no particle at 750gev than to find this non-existing particle."
It's just that the significance of this work is no longer significant.
Explain why a particle does not exist. This kind of speculation, which cannot be falsified or verified, is at most the level of a doctoral dissertation. It may help a few high-energy Ph.D. physics graduates who have not been able to get their degrees successfully, but it is far from "new physics".
Lu Zhou was silent for a long time.
After a long time, he seemed to have made up his mind and said.
"But I haven't given up."
Professor Frank said nothing, put on his hat again, and sighed softly.
"Good luck then."
