Academician Pan came to the ceremony stage with slow but determined steps.
He first laid his speech flat on the table, took a deep breath, and then looked around.
Judging from the resume.
Academician Pan can undoubtedly be regarded as a standard "young and famous".
He was named a Distinguished Young Scholar 22 years ago, and has won the Schmid Prize and the Marie Curie Outstanding Research Award in 2004.
In 2005, he was elected as one of the top ten outstanding young people in China.
Won the Fresnel Award in 2006.
In 2016.
He won the highest honor in the Chinese scientific community, the first prize of the National Natural Science Award.
In these large and small award ceremonies, Academician Pan often made various reports to big bosses.
But whether it is the graduation report as a student representative at the doctoral graduation ceremony, or the acceptance speech at the National Natural Science First Prize Award Ceremony.
Academician Pan has never been so excited...or nervous.
In a sense.
This press conference is not only related to Academician Pan’s academic status, but more importantly, it determines whether China can have a place in the high-energy physics world in the future.
In other words...
This is also a press conference involving the national destiny.
And since the fate of the country is involved, there is bound to be a battle between dragons and tigers.
Whether in front of the stage or...
Behind the scenes.
Then Academician Pan calmed down and said:
"Dear industry guests, reporters, colleagues outside the broadcast camera, and viewers, hello everyone, I am Pan Jianwei from Huaxia University of Science and Technology."
"This time I am honored to represent the Chinese Academy of Sciences and share an exciting report with you here."
"You must have heard the content of this report - yes, with the joint efforts of many experts in the Chinese physics community, we have discovered and verified the real cold dark matter!"
The moment Academician Pan spoke.
The audience outside the screen may not feel anything, but many Chinese experts at the conference were stunned.
because.......
The language used by Academician Pan is not English, but standard...
Chinese!
To know.
Under normal circumstances.
For this kind of international press conference, all speakers should use English - this is already a default rule.
So if you pay attention to those scientific conferences, you can often see Chinese, Japanese and curry-style English speeches.
But today is different.
Academician Pan's approach to using Chinese is the result of repeated discussions involving the leaders of the Academy of Sciences and a group of academicians.
After all, this is the most glorious moment in the Chinese physics community so far, and the conference venue is still our home stadium, in such an ancient building.
That being the case.
Then just use Chinese.
To put it politely, it means respecting the host language and letting the world understand Chinese culture.
What people say is whether you want to listen or not.
Anyway, these days there are simultaneous translators, which can basically follow Academician Pan’s introduction simultaneously.
By the way.
The supplier of translation equipment is one of the well-known subsidiary companies of HKUST, iFlytek.
Of course.
Precisely because it is in the Chinese language, many viewers noticed the last few words of Academician Pan:
Cold dark matter.
in the past few days.
The concepts of hot, warm, and cold dark matter can be said to be the mainstream popular science on the Internet.
Some of these popular sciences are truly objective analyses, while others are based on personal emotions or distrustful suspicions.
The rational party, represented by the blogger named [Zhajiangmian yyds], swears every day that the Academy of Sciences has discovered warm and dark matter this time, and they are playing word games from beginning to end.
But now the first words out of Academician Pan's mouth directly dispelled this possibility verbally.
In other words...
In this press conference, there is no so-called retreat.
After finishing the prearranged beginning of this part.
Academician Pan gently pressed the laser pointer in his hand, and the large screen behind him quickly changed into a vast starry sky:
"As we all know, the discovery of dark matter can be traced back to the 1970s and is an important part of cosmic physics."
"Together with gravitational waves and the Higgs particle, it is called the three major illusions that must be solved in the 21st century."
"Now that the Higgs particle has been discovered by CERN and gravitational waves have been successfully detected by LIGO, dark matter has become the lonely little unlucky egg."
"All current observational evidence proves that 99% of dark matter exists, but before that, we can still only find various hot dark matter, or... warm dark matter."
After Academician Pan finished speaking, he paused for a moment.
At the same time, the camera originally focused on Academician Pan instantly switched to Atsushi Suzuki sitting in the fourth row.
The expression on Suzuki Atsushi's face was still dull, but after the camera turned away, he couldn't help but snorted.
idiot.......
These Chinese people must have done it on purpose!
Then Academician Pan smiled very elegantly and said:
"But what's interesting is that just over four months ago, a series of very subtle things happened."
He pressed the laser pointer again, and Zhao Zhengguo's character introduction appeared on the screen:
"On a drizzling day, my colleague, Academician Zhao Zhengguo, a professor of physics at the University of Science and Technology of China and a member of the Chinese Academy of Sciences, discovered a brand new ∧ superon in the decay sample."
"This hyperon was quickly published on pdgLive. The particle number is 4685. I think some colleagues at the scene must have been impressed."
Hear this.
A few scholars in the audience nodded.
Most of these scholars are engaged in the research of baryons, so they all have certain memories of 4685 hyperons.
After all, hyperons...or baryons have always been a hot research topic.
However, the number of these scholars is not large, and more experts took out their mobile phones and logged on to pdgLive.
This chapter is not over yet, please click on the next page to continue reading! For example, Christine next to Xu Yun is the same, with her head buried in her cell phone.
at the same time.
Zhao Zhengguo, who was sitting on the other side of the fourth row, was also smiling and introducing some information to the acquaintances around him.
To be mentioned in public on such an occasion is an honor worth bragging about for a lifetime.
If you meet someone who likes to do things, he will engrave a QR code on the tombstone so that others can see the content by scanning it.
About half a minute passed.
Academician Pan looked at the audience again, and after guessing that most scholars had seen enough, he continued:
"As you can see, this particle belongs to a type of gauge hyperon. From the data point of view, it is probably the result of an ordinary journal in the first region."
"But more than half a month later, one of my students, Xu Yun, unexpectedly discovered something when he was studying this hyperon."
"He found that the energy level of this ∧ hyperon seemed a bit strange, so with the assistance of the Aurora System of the Chinese Academy of Sciences, he calculated a special probability orbit."
"Subsequently, Academician Zhao Zhengguo and I discovered a particle named 'lone point particle' based on this orbit, which is..."
"The dark matter particle we are going to announce at this press conference."
Academician Pan finished speaking.
The picture on the big screen behind him instantly changed to...
Xu Yun's mugshot.
A few seconds passed.
Christine beside Xu Yun suddenly turned her head and looked at Xu Yun in surprise:
"Hey, Xu, you haven't graduated yet, are you a student?"
"..."
Xu Yun glanced at the girl with a strange look on his face. Is this a matter of age and status?
At this time, shouldn't we ask questions such as "Are you actually related to this matter" or "Did you really calculate the probability orbit of a particle"?
This girl's brain circuit is a bit strange...
However, although his heart was full of criticisms, Xu Yun still answered obediently:
"Well, I'm still a student now—I'll be studying for a Ph.D. in physics in a few months."
Christine was silent for a moment and asked quietly:
"how old are you?"
Xu Yun was stared at by this girl and felt inexplicably a little scared, like a Fujianese seeing a Cantonese:
"I was 24 years old last year and was a graduate student."
Kristine looked at him for a few more seconds, then her shoulders slumped and she breathed out:
"Damn it, you are younger than me, geniuses should die!"
Xu Yun: "......"
Can I ask a question other than age?
While talking.
Xu Yun's cell phone, which had been set to silent in his trouser pocket, suddenly vibrated.
When Xu Yun saw this, he took out his phone and took a look and found that many people had sent him WeChat messages.
Of course.
Scientific researchers like Qiu Sheng, who have a lot of contacts with Xu Yun, basically already know the situation, so most of the people who sent WeChat messages at this time were friends outside the University of Science and Technology.
For example, the message sender at the top of the queue is Chen Shanshan, the cockroach lady we just met in the car:
[Mixed feelings.JPG, Dr. Xiao Xu, you actually lied to me!!!]
Xu Yun immediately replied:
[When did I lie to you? Didn’t I say that I calculated the dark matter? (Dog Head)]
Chen Shanshan:
【.....just wait for me】
Other than that.
Gu Qunqing from the company, Academician Li Ning, and Lin Zhenhua from far away in Yongcheng also sent messages of congratulations or praise.
But soon.
Xu Yun's good mood was dispelled by another screenshot of the live broadcast room barrage sent by Chen Shanshan.
As you can see from this picture, the barrage in the live broadcast room is unprecedentedly uniform:
【Fuck, Hina!!!】
Xu Yun: "????"
[Fuck, xxxx]
This is a barrage format that has gradually become popular in the past two years, and is generally seen in game live broadcasts.
When a player performs a highlight or cross-over operation, the barrage will flood the screen with a word that can describe the player's portrait.
For example, shit ice, shit fly, shit original, etc...
As for Chen Shanshan’s purpose in posting this screenshot...
Obviously, just to hurt each other.
And while Xu Yun was looking at the messages on his phone.
Academician Pan on the stage also continued talking:
"According to our detection, this solitary point particle belongs to the companion of the 4685∧ hyperon in nature, and its spin is a semi-odd number."
"The measured result of the decay parameter is 0.633±0.002, and the observed magnitude of the interaction with 4685∧hyperon is..."
"140Mev."
Hear this number.
Suddenly there was a commotion in the audience.
Mentioned earlier.
The property of spin belongs to the intrinsic degrees of freedom of particles.
According to the Pauli exclusion principle.
If two identical fermions have exactly the same wave function, then the distribution probability density given by their overlapping wave functions is 0.
So fermions can only have half-odd spins, that is, 1/2, 3/2, 5/2, 7/2, etc.
Electrons, protons, neutrons, and baryons are all fermions.
Mesons, photons, weak gluons, and Higgs particles all belong to bosons, and their spins are integers.
The value 140Mev belongs to the category of electrically neutral mesons, but it has the spin of a fermion...
Xu Yun spent a lot of time thinking about this issue at first, but don't forget, these people here today are all top leaders in the industry.
So it's very fast.
Except for a few bastards.
More than 95% of scholars have subconsciously produced a concept:
There is something wrong with the way this particle moves!
It's not walking or drifting, but...
Flash!
What's more important is.
Everyone already knows that the results to be released at the press conference are related to dark matter, which means they have been prepared for the answer in advance.
So now after a little extrapolation, many big guys have confirmed another thing:
This solitary point particle...
Kinetic energy is less than the corresponding static energy.
This......
It is one of the most important intrinsic qualities of dark matter!
Immediately afterwards.
On the stage, Academician Pan pressed the laser pointer again, and the screen behind him changed again.
This time.
There was a lot of data on the screen that few students could understand.
Quadratic divergence parameter: 3.445
Parity difference: 226.5 points/billion
Wave function derivative operator: 114514
flux value:17.885
Exponential mapping generator: 1.3399596
Wave function expression: ∧amp;amp;amp;amp;amp;gt;0, f(t)=Asin(wt?), Y(x)=Csin(kx) Dcos(kx).
One second later.
Including top bosses such as Higgs.
When almost all physicists saw this value, they picked up a pen and calculation paper and quickly started calculating.
Of course.
In stark contrast to the many scholars present at the conference, were the media people present and the bewildered audience outside the live broadcast room.
The expressions on their faces at this time almost all had the same thought:
What can be calculated from these numbers?
Of course.
Although there are not many professionals who are proficient in high energy physics, there are also many.
For example, some research institute employees who are unable to come, or students from corresponding majors in major universities.
As well as a very small number of civilian scientists who do have strong professional knowledge but did not enter or stay in the scientific research circle due to various reasons...
In addition, the test at this time is more about calculation ability than creativity.
So it's very fast.
On the contrary, the answer appeared first in the barrage in the live broadcast room:
[Holy shit, it’s below 0.0004, ten times faster than WIMP?]
Then very quickly.
Many people at the meeting also came up with calculation results.
For example......
Edward Witten, the most accomplished mathematician in physics today.
I saw him drawing a circle on the calculated result of 0.000193, with a thoughtful expression.
This value is called the oxika value, which is a simple tool for calculating electromagnetic interactions.
This value is far less accurate than that detected by supercomputers or precision instruments, but it has a very special place:
It can grade dark matter.
For example, the calculated value range of hot dark matter is between 0.294 and 1.
Warm dark matter is 0.00331-0.294
Cold dark matter has no lower limit, with a maximum of 0.00331.
For example, the most likely WIMP particle at present has an oxika value of 0.00106.
Of course.
The above premise is that the basic data provided is accurate and there is no fraud.
In other words...
Just judging from the calculation results.
The lone point particles discovered by the Chinese Academy of Sciences do meet the requirements of cold dark matter.
But as a top mathematician.
During the calculation process,
Edward Witten always felt that another vague thing was attracting him.
But before he had time to think about it, he was shocked back to reality by a voice behind him:
"Qiaodou Sack, Mr. Pan, how can you prove that your values are accurate?"
