The exploration of new particles in the physics session is carried out in this way. First of all, there are well-known particles and processes, and then they are used to detect "new particles". Scientists have no way to observe this so-called new particle. They just know that once there is this particle, You will see different signals in the experiment. These particles are the result of self-consistent theory and experiment.

When they speculated about the properties of this "new particle" and knew its mass, width, spin, etc., they added this particle to the model to simulate and experiment with the detection of the next "new particle". Constructed the current standard model and experimental framework of particle physics.

There are currently sixty-two particles in the standard model, including twelve kinds of lepton such as electron, positron, electron neutrino, and anti-electron neutrino. Lepton refers to spins that do not participate in strong interaction / 2 of the fermions.

There are also thirty-six kinds of quarks, such as red quark, green quark, blue quark, anti-red quark, anti-blue quark, and anti-green quark, which are the basic units of matter.

Finally, there are 14 types of gauge bosons such as photons, graviton, w + boson, w-boson, and Higgs boson. They are medium particles that transfer basic interactions, and their spins are integers. .

At present, twelve kinds of lepton, thirty-six kinds of quarks and twelve kinds of gauge bosons have been experimentally confirmed. Only the Higgs boson and graviton have not been discovered, but their properties have been theoretically Physicists speculate that the graviton is defined as a boson with a spin of 2 and a mass of zero; the Higgs boson is a boson with a spin of zero.

Therefore, as long as the properties of the Higgs boson are observed in this experiment, it can be proved that the particles long sought by physicists are real.

The set of data discovered by Dietrich came from the observation of cms. Lu Qiujian converted it to a picture where the vertical axis represents the number of events observed for a pair of photons, and the vertical axis represents the quality. It can be clearly found in the quality When the interval is 125.3 ± 0.6gev, the number of two-photon yields increases significantly.

This phenomenon is fully consistent with the current speculation on the properties of the Higgs boson, in other words, this is the conclusive evidence of the existence of the Higgs boson!

The people present, from Professor Xuft to Ludwig, were familiar with the attributes of the most Higgs boson. When they saw the results shown on this chart, they all held their breath. The heartbeat suddenly accelerated, and they knew that they were witnessing the greatest physical discovery to date in the 21st century!

"This is ..." Dietrich was so excited that he couldn't even speak clearly, when data analysis began. He looked forward to this moment, but when he did arrive, he found that he was not ready to accept it.

"Yes! This is the evidence of the existence of the Higgs boson!" Lu Qiujian stood up and patted Dietrich's shoulder hard, "You made a great discovery!"

It is true that even without Dietrich, others will find out sooner or later. Because the data produced by this experiment that can prove the existence of the Higgs boson is definitely not only such a set, but it also cannot deter the credit of Dietris.

"Congratulations, Dietrich!" Professor Xuft came over to hold his hand, and after a moment turned right to Lu Qiujian, "Lu, congratulations to you too, if we don't have you, I'm afraid we have to wait a long time before we can do that. a set of data!"

Yes, without Lu Qiujian insisting on changing the experimental plan, without him improving the efficiency of data analysis. The Higgs boson must not be discovered so soon.

Ludwig, Karl, Frederick and others came over to hug Dietrich and Lu Qiujian, and sent them their congratulations, the laboratory suddenly turned into a jubilant ocean.

"Now, let's send this result to cern!" After a short celebration, stimulated by this great discovery, everyone's fatigue was wiped out, and Lu Qiujian prepared to send this chart to the grid data In the center, everyone else went back to their seats to continue searching for data.

Since the Higgs boson really exists, then there will definitely not be only this set of data. Dietrich found this unique set of data from the observation data of cms. There are data from other observers such as atlas! The more data found, the thicker the evidence, the more likely it is to prove the existence of the Higgs boson.

The end of the delivery, Lu Qiujian did not care about the current time. Dr. Evans' phone was dialed directly, and the phone rang for a long time before it was picked up. Dr. Evans was not awakened by anger, and there was an excitement in the trembling voice, "Hey, Lu. Yes. New discovery? "

"Yes! We found a very special set of data in the observations of cms. When the mass interval is 125.3 ± 0.6gev, the number of two-photon yields has increased significantly!" Lu Qiujian reported this result quickly To Evans.

After hearing these data, Dr. Evans' breathing was significantly faster, and then the sound of Lv Qiujian's voice came from the microphone ~ www.readwn.com ~ If the data is correct, then the Higgs boson does exist. of! "

Boom ... boom ... After a messy voice, Lü Qiujian's phone made a beeping hang-up; the first sound should be the sound of a mobile phone falling to the ground, and the second sound seemed to be someone falling, Egypt Dr. Vince shouldn't be in trouble! Lv Qiujian quickly redialed the call, but the voice from the phone was unreachable.

Just when he was going to call the other people in the experimental group to get him to quickly go to Dr. Evans' room to check the situation, a strange number came over, "Lv, it's me, I just fell. ..... No, no, my body has no problems at all, it has never been better than now! ... My phone broke, and I am calling you from someone else ’s phone ... ... The data has been sent? ... Okay, I ’ll check it out immediately! "

Evans hung up the phone again, and finally the sound from the phone was a fast running sound. Lu Qiujian could even hear that Dr. Evans was wearing slippers now! It seems that he couldn't even change his clothes and went out!

With the first set of data, the second and third sets quickly appeared. After all the data analysis was completed, Lu Qiujian and his partners found several groups from the observation data of cms and atlas, respectively Evidence that can prove the existence of the Higgs boson.

"Okay, rest for one night, and we will go to cern tomorrow!" Professor Xuft said, looking at the messy children with dark eyes. (To be continued.)
