Chapter 942 Experimental Anomalies of Inert Neutrinos

Chapter 942 Experimental anomaly of sterile neutrinos~

In early June, the circular super particle collider buried hundreds of meters underground was launched.

Fusion power stations deployed nearby continuously transport huge amounts of energy into pipes made of superconducting materials.

The streams of particles are constantly accelerating and colliding, emitting sparks and fragments that cannot be captured by the naked eye, providing huge experimental data for scientific researchers on the ground.

These collision data, measured in petabytes, map out the secrets of the microscopic world that are invisible to the human eye.

These experimental data will be assigned to various groups for further analysis.

Nominally speaking, the sterile neutrino detection experiment is under the name of Xuchuan, and all research institutions, universities, and even individuals working at CRHPC can join the relevant analysis work by applying.

For scholars engaged in the theoretical physics industry, even if they cannot occupy a dominant position in the project and are just a part of screwing, many scholars have actively applied to join.

After all, this is a detection experiment of sterile neutrinos, which are currently the most likely elementary particles in theoretical physics to be one of the dark matter particles.

And even if you put aside the uncertain dark matter, it is still a mysterious particle independent of the standard model.

Its origin and detailed characterization are also what fascinate a wide range of physicists.

However, what confuses many scholars involved in this detection and analysis experiment is that Professor Xu Chuan, as the general person in charge of the sterile neutrino detection experiment, has never appeared from beginning to end.

June 10th, the fifth day after the launch of the CRHPC Circular Super Particle Collider.

In the conference room, after finishing the meeting to process the data of this sterile neutrino collision experiment, Lin Feng breathed a long sigh of relief, announced the dissolution of the meeting and leaned back lazily on his chair.

When Xu Chuan chose to put down the challenge and leave this collision experiment to their control, they were destined to be busy.

When detecting an unknown mysterious particle, especially when going deep into areas that humans have never understood, everything must be done carefully and verified over and over again before adjusting the experimental direction for the next collision.

Without Xu Chuan at the helm personally handling these tasks, I have to say that there are indeed many opinions within CRHPC.

In particular, some scholars from Western countries were not very convinced of his command.

Fortunately, there is also the board of directors of the CRHPC organization behind him, and his former mentor Edward Witten will also help to stand up.

In addition, so far, the detection of sterile neutrinos has been progressing smoothly, so he can barely control the relevant experiments.

In the conference room, after sorting out the report documents in front of him, Edward Witten looked at his other student and asked curiously.

"Speaking of which, I haven't seen anyone from Xu Chuan recently. Has he left here?"

Lin Feng shook his head and said: "That's not true, he is still with CRHPC."

"Um?"

Hearing this answer, Witten showed a trace of doubt on his face and couldn't help but ask: "Then what is he doing? Isn't he even interested in the sterile neutrino detection experiment?"

"This is the result of his discovery many years ago."

Lin Feng thought for a while and said, "I really don't know exactly what he is studying. He didn't say."

"But judging from the fact that he has been staying in his office recently, he may be working on some theory?"

Shrugging, he looked at Witten and continued: "If you want to know, I'm afraid you have to ask him yourself."

"Some theory?"

Witten thought about it carefully, nodded and did not continue to ask any more questions, nor did he say that he wanted to go and take a look.

In his view, if there were no other more important things, Xu Chuan would not give up the sterile neutrino detection experiment.

Because this is not only the most likely particle of dark matter, but also a clue that he personally found from the LHC collider a few years ago.

Something that would allow him to put aside the sterile neutrino detection experiment and study it would be at least two levels more important than the complete discovery of sterile neutrinos.

In this case, there is no need for him to disturb this student's research work. He will find out when he comes out.

Of course, Witten still had some guesses about what Xu Chuan might be researching.

The cutting-edge theory that allows him to put aside the detection of sterile neutrinos and concentrate on research, apart from the Riemann Hypothesis, is probably the void field theory.

The research on these two cutting-edge theories in mathematical physics, no matter which one has a breakthrough, will be epic for the promotion and development of their respective fields.

Xu Chuan’s dedicated research has not interfered with the normal operation of the CRHPC institution, nor will it interfere with the experiments of the Circular Super Particle Collider.

Collision detection experiments for sterile neutrinos are still proceeding steadily and orderly, and each collision will bring huge amounts of information data.

These experimental data will be initially processed through the supercomputing center established nearby and the cloud computing resources established by the CRHPC institution, and then sent to the hands of various research groups.

The detection of sterile neutrinos is quite difficult.

First of all, the mass of neutrinos is extremely small and almost negligible. Their diameter is about 10^-20 meters to 10^-18 meters, which is much smaller than the size of the nucleus.

More importantly, neutrinos have no electromagnetic force or strong nuclear force with other particles, only weak nuclear force and gravity, and the interaction form is extremely isolated and difficult to explore.

It is even more difficult to observe neutrinos through colliders.

Because neutrinos hardly interact with other matter, most detectors cannot capture them.

Moreover, it is very difficult to distinguish neutrinos from the many particles and radiation produced by the collider.

In order to solve this problem, Xu Chuan joined forces with many top physicists to upgrade and optimize the superconducting ring field detector and kinetic energy trajectory tracking detector of the circular superintense particle collider.

At the front end of these two large detection trackers, there is an independent detection laboratory. The connection area between the laboratory and the detector is hundreds of meters away, and there are various materials such as concrete stone walls and metal plates for filtering in the middle.

For most particles, it is difficult to pass through such a heavy filter.

But neutrinos are different. Lightweight and high-energy neutrinos tend to fly in the direction of the beam tube (called "forward") and escape from the blind spot.

And these neutrinos will pass through the stone wall all the way and reach the forward detection laboratory.

Here, nearly a thousand layers of nuclear latex sheets and tungsten plates are deployed alternately to distinguish different types of neutrinos and measure their properties.

This is one of the most critical detection equipment for the detection of inert neutrinos.

Of course, in addition to inert neutrinos, the forward detection laboratory is also responsible for the mission of detecting other unknown particles.

For example, other forms of neutrinos, dark matter particles, axions, etc. may exist.

These particles, which also occupy the mainstream speculation in the physics community, are also one of the main directions that the CRHPC organization is looking for.

June 15th, the tenth day after the launch of the inert neutrino detection project.

In the conference room, Lin Feng repeatedly flipped through the sorted experimental data, frowning.

The detection of inert neutrinos was quite smooth at the beginning. After integrating Xu Chuan's research work at CERN a few years ago, they captured more than three-digit signal data from the collision data in just one week, and once pushed the confidence level to above 4.2Sigma.

But with the increase in confidence and the increase in collision energy level, abnormal phenomena appeared.

According to the inert neutrino and warm dark matter theory established by Xu Chuan, although the mass of neutrinos is extremely difficult to measure, it can cause reactions caused by its interaction with protons at high energy levels, and then indirectly detect neutrinos.

Simply put, it is equivalent to using a string of proton beams to randomly collide inert neutrinos that were originally unobservable in the void.

In this process, inert neutrinos will interact with proton beams, releasing energy all at once, and will illuminate a nearly spherical area.

This is the detection method proposed by Xu Chuan, and the CRHPC organization is also exploring it in this way.

Theoretically, the energy level of inert neutrinos and fixed types of protons at high energy levels exceeding 17Tev is fixed.

But the analysis data in recent times has shown abnormalities.

Holding the Daritz diagram in his hand, Lin Feng looked at it repeatedly several times. Looking at the series of green dots whose energy levels were about to soar to 28.9Tev, he couldn't help rubbing his head with a headache.

According to predictions, this phenomenon should not occur.

Theoretically, the mass of inert neutrinos is larger than the three conventional neutrinos. Theoretically, the energy level produced in the proton collision experiment should also be higher.

But no matter how high it is, the energy level of the collision experiment conducted by the collider is controlled.

The mass of inert neutrinos cannot increase or decrease for no reason, and it will not be actively accelerated by the large-scale particle collider, and it is even more impossible to suddenly increase the energy level.

But now, its energy level is obviously higher than the 17Tev energy level, and the magnitude is almost doubled.

The result of this abnormal energy level obviously exceeded everyone's expectations.

Staring at the Dalitz diagram in his hand, frowning and thinking for a long time, Lin Feng took a long breath and asked: "Regarding the phenomenon of abnormal energy levels, although we don't have a clear explanation yet. However, our results of the exploration of inert neutrinos are completely consistent with the previous findings of Professor Xu Chuan at CERN."

"This means that at least in the detection experiment of inert neutrinos, we are on the right track."

At the conference table, Professor Gunnar Hamilton from the German Planck High Energy Physics Laboratory shook his head and said: "But if the energy level data is mixed with abnormalities, we can't accurately make a Daritz diagram with a confidence level of more than 5 sigma."

"We can't ignore the appearance of these low-energy inert neutrino and proton collision signals as background noise."

Hearing this, Lin Feng pinched his nose with a headache, and asked his former mentor Edward Witten with some tentative views: "Professor Witten, what do you think?"

On the side, Edward Witten held the report document in his hand and said with a thoughtful look:

"Is it possible that, like the three conventional neutrinos, electron neutrinos, muon neutrinos and tau neutrinos, dark matter can also produce different types of neutrinos under high-energy collision interactions?"

Across the conference table, Professor Gunnar Hamilton touched his chin and said, "Another neutrino? Or some dark matter particle that we have not yet discovered?"

"This is indeed very likely, and the possibility is not low. After all, there are three types of conventional neutrinos. Theoretically, there may be more types of dark neutrinos formed when dark matter interacts."

"However, the current exploration data for it is too scarce, and we need more time data to analyze it."

After a slight pause, he looked at Lin Feng and said with a smile on his face Asked: "Mr. Lin Feng, may I ask when the next collision experiment of the CRHPC Circular Strong Particle Collider is scheduled?"

Lin Feng: "The pipelines, superconducting circular detectors and forward detectors of the collider all need to be repaired. We will probably need about ten days to start the next collision experiment."

Hearing the answer, Professor Gunnar Hamilton smiled and said: "If I remember correctly, according to the rules of the CRHPC organization, scholars or research institutions that discover a new phenomenon have priority to apply for the next collision experiment of this type of phenomenon."

This priority, whether in the CRHPC organization or the former CERN organization, is also a means to protect the rights and interests of scholars who discover new physical phenomena.

After all, it is impossible for a scholar to discover an abnormal phenomenon and then make certain achievements, but be taken away by others through connections.

Lin Feng nodded and said, "Of course."

Hamilton: "On behalf of the Planck Institute for High Energy Physics, I will apply to the directors of the CRHPC organization for the next observation experiment on the abnormal energy levels of high-energy inert neutrinos."

Lin Feng: "You need to go through the application process for this."

Before he finished speaking, the door of the conference room was suddenly pushed open.

Xu Chuan, who had not participated in the inert neutrino exploration experiment for almost a month, walked in from outside, attracting the attention of many people.

"Fuck, you finally came out of your office?"

Seeing Xu Chuan, Lin Feng, who was presiding over the meeting, was stunned for a moment, and spoke with a tone like a woman in the boudoir in surprise.

In the past half a month, he almost died of exhaustion in presiding over the collision detection experiment of inert neutrinos on behalf of Xu Chuan.

Not only was he responsible for the original experimental data analysis work, after all, he was also a member of the inert neutrino detection experiment team, and he also had to preside over various experimental meetings, organize relevant data, etc.

When he was busy, Lin Feng really wanted to go to Xu Chuan's office and pull him out to do his own thing.

Do it, do it, do it, do your sister's research all day long!

Have you ever considered other people's feelings? !

Xu Chuan smiled and nodded, saying: "I received the latest data from the inert neutrino detection experiment, and came to see the situation."

Looking at the dark circles and fatigue on Brother Lin's face, he smiled and patted his arm, saying: "You have worked hard during this period, I will take over the next work."
