Chapter 261: The Greatest Physical Discovery of the 21st Century

The exploration of new particles in physics is carried out in this way, first there are familiar 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, they will see different signals in the experiment, and these particles are the result of self-consistency between theory and experiment.

When they deduced the properties of this "new particle", knew its mass, width, spin, etc., and then added this particle to the model, and then simulated and experimented with the detection of the next "new particle", and the cycle was repeated, constructing the standard model and experimental framework of particle physics.

At present, there are a total of 62 particles in the Standard Model, including 12 types of leptons, including electrons, positrons, electron neutrinos, and anti-electron neutrinos.

There are also 36 kinds of quarks, such as red quarks, green quarks, blue quarks, anti-red quarks, anti-blue quarks, and anti-green quarks, which are the basic units of matter.

Finally, there are fourteen gauge bosons, such as photons, gravitons, W+ bosons, W-bosons, and Higgs bosons, which are medium particles that transmit fundamental interactions, and their spins are all integers.

At present, 12 leptons, 36 quarks and 12 gauge bosons have been experimentally confirmed, only the Higgs boson and graviton have not yet been discovered, but their properties have been speculated by theoretical physicists, the graviton is defined as a boson with a spin of 2 and a mass of zero, and the Higgs boson is a boson with zero spin.

Therefore, as long as the properties of the Higgs boson are observed in this experiment, it can be proved that this particle that physicists have been looking for for a long time is real.

The data discovered by Dietrich came from the observation of CMS, and Lu Qiujian converted it into a picture of the number of events observed by the vertical axis marker representing the number of photons observed and the vertical axis mark representing the mass, and it can be clearly found that the number of two-photons produced in the mass range of 125.3±0.6 GeV increases significantly.

This phenomenon is completely in line with the current physics 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 Schiff to Ludwig, knew the properties of the most Higgs boson by heart. They all held their breath and their hearts beat faster when they saw the results shown on this chart, knowing that they were witnessing the greatest physical discovery of the twenty-first century so far!

"This is," Dietrich couldn't even speak with emotion, he had been looking forward to the moment when the data analysis had begun, but when he did, he found himself unready to accept it.

"Yes, this is the proof of the existence of the Higgs boson!" Lu Qiujian stood up and patted Dietrich on the shoulder, "You have made a great discovery!"

Admittedly, even without Dietrich. Sooner or later, others will find out, because there is certainly more than one set of data from this experiment that proves the existence of the Higgs boson, but that doesn't take away from Dietrice's credit.

"Congratulations, Dietrich!" Professor Xuft came over and shook his hand, and after a moment turned to Lu Qiujian, "Lu, congratulations as well, if it weren't for you, I'm afraid we would have to wait a long time for such a set of data!"

Yes. Without Lu Qiujian's insistence on changing the experimental protocol, and without him improving the efficiency of data analysis, the Higgs boson would certainly not have been discovered so quickly.

Ludwig, Karl, Frederick and others once came over to hug Dietrich and Lu Qiujian and congratulate them. The laboratory suddenly turned into a sea of jubilation.

"Now, let's send this result to CERN!" After a brief celebration, the fatigue of everyone was swept away by the excitement of this great discovery. Lu Qiujian prepared to send the chart to the grid data center, and the others returned to their seats to continue looking for data.

Since the Higgs boson really exists, it certainly won't be the only set of data. Dietrich is finding this unique set of data from CMS observations, as well as data from other observers such as ATLAS! The more data is found, the thicker the evidence will be, and the more evidence will prove the existence of the Higgs boson.

At the end of the sending, Lu Qiujian didn't care about the current time, and directly dialed Dr. Evans's phone, and the phone rang for a long time before it was picked up, Dr. Evans did not have the slightest anger to be woken up, and there was a sense of excitement in his trembling voice, "Hey, Lu, is there a new discovery?"

"Yes, we found a very special set of data in the CMS observations, and when the mass interval is 125.3±0.6 GeV, the number of two-photons produced increases significantly!" Lu Qiujian quickly reported the results to Evans.

After hearing this data, Dr. Evans's breathing increased significantly, and then Lu Qiujian's determined voice came from the microphone, "If the data is not wrong, then the Higgs boson does exist!"

After a chaotic sound, Lu Qiujian's phone made a beep hanging up sound; the first time it was supposed to be the sound of the phone falling to the ground, and the second sound seemed to be someone falling, Dr. Evans shouldn't have had an accident! Lu Qiujian hurriedly dialed it again, but the voice on the phone could not be connected.

Just as he was about to call the rest of the experimental group and ask him to hurry to Dr. Evans's room to check on the situation, an unfamiliar number called, "Lu, it's me, I just fell down, no, no, no, my body has not had the slightest problem, it has never been so good as it is now! My phone was broken, and now I am calling you from someone else's phone, and the data has been sent?" Okay, okay, I'll go see it right away!"

Evans hung up the phone again, and the last sound that came from the phone was the sound of a fast running, and Lu Qiujian could even hear that Dr. Evans was wearing slippers now!

With the first set of data, the second and third groups quickly popped up, and when all the data analysis was completed, Lu Qiujian and his partners found several sets of evidence from the CMS and ATLAS observations that could prove the existence of the Higgs boson.

"Alright, rest for the night, and we'll go to CERN tomorrow!" said Professor Schifft, looking at the children with messy hair and dark eyes. (To be continued.) )
