Chapter 958 Cτ particle~

The internal acceptance report meeting of the 125Tev energy level collision experiment soon entered the question-and-answer session.

For the last result of this inert neutrino and dark matter particle detection experiment, many people raised their hands to ask questions.

This is the first time that the physics community has verified particles beyond the standard model, and it is also the first time that human civilization has explored the mysterious field of dark matter. No one will give up leaving their name and glory on this historical monument.

From the 35Tev energy level to the 100Tev energy level collision experiments, they have passed the acceptance report meeting and have their own owners, and 125Tev is the last one, and it is still the one that has no owner.

For Nanjing University and Shanghai Jiaotong University, it is impossible to give up this hard-won opportunity easily.

On the report platform, Professor Zhao Hu answered every question calmly and calmly, striving to be perfect.

Time passed bit by bit, and the question-and-answer session lasted from 9:40 to 10:30 in the morning, and the battle lasted for nearly an hour before it stopped.

In the audience, the acceptance team of the CRHPC organization in the front row exchanged opinions with each other, and after confirming that there were no problems, they announced that the acceptance report of the 125Tev energy level collision experiment jointly submitted by Nanjing University and Shanghai Jiaotong University had passed smoothly.

When the sentence "125Tev energy level inert neutrino and dark matter collision experiment" was officially accepted by the CRHPC organization, the applause in the venue was thunderous.

Applauding, Xu Chuan took over the stage from Professor Zhao Hu of Shanghai Jiaotong University.

After expressing respect and gratitude to the two universities and related research institutions that made this contribution again as usual, he glanced at the thousands of listeners in the venue, and the corners of his mouth raised a little.

Facing these pairs of expectant or solemn eyes, he spoke slowly in a clear voice.

"Seven years ago, when I was still studying at Princeton University, I went to CERN for further studies."

"In a collision experiment at the 13Tev energy level, I discovered some abnormal phenomena, and finally confirmed that in the vast universe, in the microscopic world, there is a kind of particle that we cannot see."

Without any extra words, Xu Chuan went straight to the point and continued.

"This is a particle that exists in the 120um (rφ direction) beam z observation data of the anti-helium-3 nucleus in the inner tracking system. It may be the legendary dark matter, or it may be some kind of particle that we have not explored before."

"But due to the limitations of the detection equipment and technology used at the time, we can only see part of the information of this particle, but cannot see its full picture."

"And now, in the CRHPC institution, we have a more powerful particle collider. Starting from the energy level experiment of 13Tev, to 17Tev, then to 35Tev, to the final 125Tev"

"Step by step exploration, step by step experiment, let us finally grasp the full picture of this mysterious particle, and also gain more information about other particles similar to it."

At this point, Xu Chuan paused slightly, his eyes swept across the audience, looking at the silent lecture hall, looking at the countless people who raised their heads waiting for answers, he smiled, and continued with a relieved tone.

"It is an honor to be here today, representing CRHPC and the theoretical physics community, to announce our latest research results to everyone."

Hearing Xu Chuan's words, the entire venue became noisy, and the sound of discussion was heard almost everywhere. Everyone showed a look of surprise on their faces, but there was a hint of excitement and expectation in their eyes.

The acceptance report meeting of the 125Tev energy level collision experiment is not the end of the inert neutrino and dark matter particle detection experiment. Although today's acceptance report meeting will make everyone look forward to it, what everyone is more looking forward to is when the scholar standing on the stage at this moment will be able to conduct a complete report work.

After all, the former is only a phased result, and the latter is a real breakthrough.

However, even so, most people probably have never thought that the person in front of them can conduct this report work at today's acceptance report meeting.

After all, even if it is to organize the experimental data of these different energy level regions, it takes time.

What's more, when facing inert neutrinos and dark matter particles that are beyond the standard model?

No matter how long it takes to verify them repeatedly, it is not too much.

Xu Chuan glanced at the audience below the stage, with a happy smile on his face, and continued.

"Seven years ago, I asked everyone a question at the stage report meeting on inert neutrinos, that is, when facing the vast universe, what is the biggest mystery that human science has encountered so far?"

"And today, I can stand here to answer this answer!"

As he said, he turned to the blackboard on the report table, picked up the marker from the pen basket, and wrote three big words on it.

[Dark matter! ]

"This is a kind of 'matter' that exists in the universe and is difficult to directly observe and see with current human scientific means. It is the main component of cosmic matter and constitutes a very small part of the currently visible celestial bodies and most of the invisible structures."

"For example, supermassive black holes in the centers of some galaxies, dark matter stars, some quasars, etc."

"I am not the first person to propose this concept. As early as 1922, Professor Kaptan proposed that invisible matter may exist around stars, affecting their motion and structure.

"In the following century, countless scholars in the field of physics tried to find this invisible matter that affects the structure of the universe and the operation of galaxies."

"For example, in 1933, the astrophysicist Zwicky used spectral redshift to measure the motion speed of each galaxy in the Coma galaxy cluster relative to the galaxy cluster."

"Using the virial force theorem, he found that the velocity dispersion of galaxies in the galaxy cluster is too high. The gravitational force generated by the mass of the visible galaxies in the galaxy cluster alone cannot bind them to the galaxy cluster. Therefore, there should be a large number of galaxies in the galaxy cluster. Dark matter is at least a hundred times more massive than visible galaxies."

"Or maybe in 1959, two professors, Kane and Walter, studied the relative motion between the Andromeda Nebula and the Milky Way, which are attracted to each other. Through the speed at which they approach each other and the distance between them, they deduced that we humans are in the Dark matter in the Milky Way galaxy cluster is about ten times more massive than visible matter, and so on.”

“Although there is so much evidence that there is a substance in the universe that we humans cannot see that is affecting the operation of the universe and the structure of galaxies, but unfortunately, before today, the particles that make up these invisible substances Its properties are still unknown. "Whether this mysterious particle actually exists is a difficult question to answer."

"After all, we cannot be sure whether there is really a stable particle in the universe that is uncharged, does not have strong interactions, and only has weak gravity and weak interactions."

"We can't see it directly with a collider or other equipment."

“An invisible, incomprehensible particle whose existence is puzzling to any civilization.”

"But today, after experiencing countless collision experiments and sacrificing countless particles, we finally found one of these mysterious particles!"

"Sterty neutrinos!"

After a slight pause, Xu Chuan wrote the name on the blackboard and continued:

"According to the classification of void field and dark matter theory, it is a medium-mass dark matter particle that constitutes part of the structure of our universe and is widely distributed in every space and time."

"Even right now, it's like a ghost, moving through all of us."

"It does not have a strong interaction force or an electromagnetic interaction force. Its properties are highly stable and almost do not react with ordinary matter. But it will also pass through gravity and some forces or forces that we have not fully explored yet. Form interacts with other matter."

"The most important thing is that it can release a large amount of dark energy by releasing a smaller dark matter particle when breaking the void."

"This is what drives the expansion of our universe!"

The incredible sounds from the audience gradually spread, and many people's faces had a trace of surprise written on their faces that was stronger than before.

It can be said that everyone present today has seen the theory of void field dark matter, but it does not include the paragraph reported in front of me.

Dark matter particles are related to dark energy, and dark energy is released when dark matter particles release a particle with a smaller mass.

Although this explanation is indeed logical, it is also consistent with the phenomenon that the universe is still expanding or even accelerating from more than 10 billion years ago to the present.

But most of them didn't understand why Xu Chuan came to such a decisive conclusion.

After all, for current physics, although the existence of dark matter particles has been proven, how many forms it has and whether it is really related to dark energy is still a mystery.

Noticing the expressions on these people's faces, Xu Chuan smiled faintly, turned and walked to the blackboard behind him, picked up a marker and wrote on it:

【Cτ】

"The Cτ particle is the sterile neutrino. This is my simple name for it. Of course, this is a temporary symbol for the convenience of description. Maybe I will modify it in the future."

"But that's not the most important thing right now."

"Importantly, through the collection of information from collision experiments from the 13Tev energy level to the 125Tev energy level, it is shown that Cτ sterile neutrinos exist in collision experiments in a certain energy level range."

"Next, I will use collision experimental data from multiple energy levels such as 13Tev, 17Tev, 35Tev, 50Tev, etc. to explain how sterile neutrinos are transformed into other dark matter particles of the same energy level and mass level through the void breach phenomenon. , and fission into dark matter particles with smaller mass and lower energy levels.”

"I will write as detailed as possible, but I cannot guarantee that everyone present will fully understand my theory."

"It's impossible after all."

After finishing his words, Xu Chuan took a deep breath, turned to look at the blackboard, raised his right hand and wrote on the blackboard:

"The Cτ sterile neutrino is a dark matter particle. Before we can fully understand its properties, we need to examine whether it is stable on the time scale of the age of the universe. The Cτ sterile neutrino fissions into smaller-mass particles through the void breach effect. mode, the corresponding lifetime can be written as.”

“Cτ=2.88*10{Ms/0.1KeV}·{θ/10}KeV”

“Where Ms and θ are the mass of the sterile neutrino and the mixing angle between it and the smaller dark matter particles formed by fission.”

“From this we can see that the lifetime of the sterile neutrino in Cτ is much greater than the age of the universe, but this does not conform to my prediction in the theory of void field and dark matter.”

“So I introduced the void breaking effect in this process, which I wrote as the X effect, which occurs in the dark matter particles that pass through the high-energy environment or can undergo fission. Through this type of effect, massive dark matter particles will actively fission, releasing a large amount of dark energy and smaller dark matter particles.”

“The expansion effect of the universe confirms from the side that massive dark matter particles are always fissioning. They released a large amount of dark energy in the process, driving the expansion of our universe.”

“From this, we can imagine that in the early universe, massive dark matter particles and the dark matter particles formed by The clumps or stars composed of massive dark matter particles are more numerous and denser than they are now. "

"It is because they are constantly passing through the void breaking effect that they have promoted the development of the universe and space, forming our current universe, and are still pushing outward."

"By observing the inert neutrino Cτ particles in multiple energy level regions, we can confirm that the fission energy level region of the Cτ particle inert neutrino is Cτ=XCτ·13TeV|△m/41|XCτ·17TeV."

"That is, in the energy level region of 13Tev to 17Tev, the inert neutrino will naturally fission a dark matter particle with a smaller mass through the void breaking effect, and release a large amount of energy. "

"And the calculation formula for the dark energy it releases is."

PS: It's the end of the month, and I'm begging for the monthly tickets in the hands of the big guys. There will be another chapter later. After writing this plot,
