As long as the relevant matters of antimatter engineering are not exposed, Liu Feng will naturally not cherish himself.

On the contrary, in academics, he is very willing to point out some people's questions, and he even spends a fixed time every day on the Internet, checking his mailbox, answering questions for scholars from all over the world, and exchanging academic knowledge by the way.

Although, in fact, most of the emails are his initiative to answer people's questions, but from these questions, Liu Feng is not without gains, many seemingly simple and ordinary questions, can bring him a refreshing feeling, for his work is not small, this is also the reason why he tirelessly insists on taking time out to answer these emails from all over the world on the Internet.

Of course, the result is that he has never met many scientists, but on the Internet, he has been friends for a long time, and Professor Liu's good reputation of being "approachable" and "uneducated" has gone viral in the academic world; both his reputation and status are like playing a game to upgrade, and it can be seen that he has improved.

So, Liu Feng stretched out his hand and said very generously: "Mr. Siemens, even if you ask questions, as long as I can answer them, I will know everything and say everything." ”

Seeing this, Siemens was quite surprised.

He has the intention of inquiring about other people's information, even if people don't treat him at all, it's completely okay, and the reason why he is straight to the point is also a small means, because he seems to be frank.

In his heart, he nodded secretly, and sure enough, he was worthy of the famous Professor Liu, and the grandmaster's bearing was unobstructed.

You're welcome either:

"When we were producing superconducting electromagnets, we stumbled upon some strange 'interfaces' reserved for these electromagnets, which are different from the LHC superhadron collider at CERN.

I see!

Liu Feng smiled, and he was a lot less wary of this guy in his heart.

The 'interfaces' reserved by superconducting electromagnetics were indeed left by him in order to connect to other instruments and equipment, and these instruments were naturally inseparable from the production of antimatter, but he had already had enough convincing excuses to block other people's curiosity.

In fact, he really didn't want to reveal any design secrets of the new super collider as a last resort, but who made it impossible to produce these electromagnetic stones in China?

Since he chose to publish the design parameters generously, he naturally didn't think about 'hiding' anything, but he really didn't expect that the people of country D would find out so quickly, and they were very curious about it!

I have to say that the rigorous work attitude and sensitivity to data of the people of country D are really admirable.

After thinking about it, Liu Feng explained: "In fact, there are two main considerations for designing these 'interfaces'. Mr. Siemens, you are also a member of CERN, and no one knows the LHC better than you, right?"

"LHC?" Siemens was quite complacent, although he was full of doubts, "Of course, this is the world's largest and most advanced hadron collider so far, and most of the parts of the LHC are provided by Siemens." ”

"But I think there are still big limitations to the design of the LHC!"

Liu Feng took a sip of tea from the teacup, and saw that Siemens' eyes were a little jumping, obviously unconvinced, but he still behaved very respectfully, and the corners of his mouth hooked up a smile.

If someone who is very familiar with him sees it, they will definitely know that this guy has started to fool people again.

Limitations?

Mark Bivis and his assistant glanced at each other, and they could see the confusion and excitement in each other's eyes.

What is confusing is that the LHC is the world's most advanced Large Hadron Collider, when it was originally designed, it used the world's best technology and the best materials.

In this regard, Bivais, who has served as a construction engineer at LHC, is very confident and subconsciously very skeptical, but the person in front of him can be said to be the most powerful basic physics boss in the world.

That's what excites them!

"I want to hear about it!"

Seeing that the other party's interest was aroused, Liu Feng nodded with satisfaction, and explained in the tone he had learned from Zhang Juzuo of the Battle Suddenly Bureau:

"Since the perfection of the Grand Unification Theory, many new physics have been discovered by colliders around the world. In the first phase of the LHC's search for new physics, there was already a major achievement, that is, the discovery of the Standard Model-like Higgs particle with a mass of around 126 GeV! This is something that no other collider in the world has ever discovered, and in this respect, the LHC is the most advanced hadron collider in the world. ”

Siemens nodded.

Since the perfection of the grand unified theory, physicists have proposed a variety of new physical models on this basis.

However, the supersymmetric model (SUSY) has been the most widely studied model, because physicists are eager to verify the existence of supersymmetry through experiments, that is, the observation of supersymmetric particles.

As a result, from the end of last year to the beginning of this year, after several months of thorough preparation, the LHC finally discovered the results of the Standard Model-like Higgs particle, which caused a great sensation in the field of high-energy physics, and the relevant papers and materials were widely disseminated in the high-energy physics community.

It can be said that this is the most intuitive and effective proof of this since Liu Feng perfected the theory of great unification!

Its discovery has completely tested the correctness of the Great Unified Theory and advanced the entire new physics to a new level!

So much so that someone at CERN excitedly said that this is the greatest discovery of the 21st century!

When the results came out, Siemens was also very excited, because since then, countries around the world have further increased their investment in the super collider, so that Siemens' orders have been rising......

Thank you, Professor Liu!

However, CERN has encountered a lot of problems recently, and these problems are one of the reasons why he attaches so much importance to Huaguo's Super Collider, or Liu Feng!

However, the results of the LHC Run-I experiment have excluded the mass of the glutrino Gluino to O(1TeV), the mass of Stop and Sbottom to O (600 GeV), and the mass of the electroweak supersymmetric particle to O (300 GeV). ”

"Although some new physical phenomena have been discovered that are about 3σ beyond the background of the Standard Model, such as the signs of exceedance found by the ATLAS experimental group near the mass of the Z boson, no new particles have been discovered. ”

"The fundamental reason for this is entirely because the super collider built before the Great Unified Theory has gradually failed to keep up with the development of the times, and they have fallen behind!"

Theoretically, the most common kinetic variables used to find supersymmetric particle signals on the Large Hadron Collider LHC include HT and meff, which are used to distinguish between supersymmetric signals and Standard Model backgrounds.

where HT refers to the scalar of the transverse momentum of all observed particles, while meff=HT+ETmiss, where ETmiss represents the lost energy. HT usually represents the mass of the final parent particle, and the variable meff is mainly distributed on the supersymmetric scale for the supersymmetric signal and at a lower scale for the Standard Model background, so HT and meff can be used to distinguish the supersymmetric signal from the Standard Model background.

However, although the experimental results of LHC Run-I have been very accurate, and both HT and meff have reached a very precise level, these days, there is still no 'new particle' on their CERN side, which is definitely a very big blow to the entire high-energy physics community!

Could it be that the great unified theories of others have opened the door to theories for you, but you experimenters can't even verify them? So much so that many people are doubting whether the earth's current scientific development can continue in the new physics.

Siemens also knows that the LHC Run-II is currently planning to start operation, its centroid energy will reach 13 TeV, and the cross-section of the supersymmetric particle will be greatly raised, and it is very likely that something will be discovered, but to be honest, many people do not have much hope for this......

Could it be that in addition to the innovation of the super collider, high-energy physics will not be able to develop again?

However, how easy is it to replace the supercollider in a short period of time?

Shaking his head: "Professor Liu, you should know that with the scientific development of the world today, whether it is materials or processing, there is no way to make more innovations in the development of the super collider, even if the super collider is under construction in your country, except for the size and energy, I am afraid that there is no substantial improvement......

Mark Bivis also agreed with this, but he heard another meaning from Liu Feng's confident words: "Professor Liu, do you have a solution, or is it necessarily related to the interface you reserved on the superconducting electromagnet?"

"Of course there is a connection!" Liu Feng nodded appreciatively, looking teachable, "In fact, in addition to improving the accuracy of the Super Collider, we also have a way to have a more significant phenomenon than the LHC Run-I when the integration brightness is not too high in the early stage of operation!"

"Do you really have a way to solve it?!" Siemens also raised his head, this trip to China is really the right one?!

"There is a way, but whether it is right or not, it will not be convincing until the construction of the super collider on our side is completed. Liu Feng shook his head, looking like he wanted to speak and stopped.

If there is a way, then you should say it quickly!

Mark Bivis's eyes were red, and he leaned forward and stared at Liu Feng with blank eyes......

"Well, anyway, the answer will be announced sooner or later, and since you are interested, then I will introduce it to you in advance. ”

Whetting his appetite, Liu Feng explained,

"We can further depress the multi-jets background of the Standard Model by adding a set of ultra-laser collision devices so that the final signal contains a large number of leptons or photons. ”

"There are a number of complex variables involved in this that are closely related to the kinematics of the decay process of heavy supersymmetric particles with masses around 1 TeV, because these variables can increase the sensitivity to the generation of heavy supersymmetric particles, further depressing the multi-jets background of the Standard Model. ”

"In this regard, we use the sub-minimum supersymmetry model to require the branch ratio of the cascaded decay q→qX2-0 → qZX1-0 of the Squark to be close to 100%, respectively, and the generation of the first two generations of Squark pairs can explain the Z-peak exceedance signs observed by the ATLAS experimental group!"

At the same time, the mass spectrum is required to be compact, and the branch ratio of nearly 100% requires x10 to be singlino and x20 to bino, which can also meet the other experimental results of the LHC Run-I stage. ”

After all, Mark Bivis is not a professional researcher of high-energy physics, and the more he listens to these data, the more confused he becomes, and he only feels that one head is bigger than three.

As for his assistant Nick Nigel, he is even more confused, although this guy is disdainful of China's high-end manufacturing industry, and even has a lot of contempt for China's scientists, but for the physics boss in front of him who is admired all over the world, he does not dare to underestimate it at all, and even after such a contact, he admires it even more.

How can there be such a powerful person in this world?

People can calculate and solve the problems encountered by LHC just from some 'just words' published by CERN, but those people at CERN are like wine bags and rice bags!

Awesome! Awesome! This is the real master!

Fortunately, Siemens is also the core figure of CERN, Liu Feng's things, he can barely listen to them, however, because of this, he scratches his ears and scratches his cheeks, no longer doubts, and even can't wait to run to CERN right away, so that those people can immediately verify Professor Liu's views!

He asked blankly, "Professor Liu, are there really these variables you mentioned?"

"Of course, these variables include αT, razor, mT2, mT2W and mCT, and I have already written a paper and plan to publish it in a journal recently, but I can only calculate these five groups with the existing data, and there are many unknown variables that must be modified by the super collider before they can be further calculated. ”

Liu Feng satisfied his thirst for knowledge, and his heart moved, and he also added a fire to the boat, and 'made up' some data that only existed in his mind to prove that what he said was based on facts!

Of course, these things can definitely stand up to scrutiny, after all, it is the result of his collision by simulating the collision of the super collider in his mind, and as for whether the construction of super colliders in other countries will be led astray by him, it is not for him to take the blame......

"The interface I reserved on the superconducting electromagnetic, on the one hand, is to install a set of superlaser collision devices, on the other hand, to reserve a set of additional superconducting electromagnetics for the future, I have a hunch, the existing supercollider magnetic field strength, may not be enough......"
