Interesting result from CERN: Are there traces of new heavy particles?

Scientists from the European Organization for Nuclear Research are very interested in this. Did they record the decay of the heaviest unknown new particle so far unknown? This can be shown by data from two independent experiments. However, it is not yet certain, and the interesting result is probably a coincidence.

The data obtained from two experiments (ATLAS and CMS) conducted at the Large Hadron Collider kept physicists awake at night. In the two detectors, the data is collected independently, which can prove the existence of unknown particles. This will be not only the unknown part so far, but also the most difficult part. Its mass should be 750 GeV (GeV is 1 billion electron volts). Therefore, the weight of the new particle will be more than 4 times that of the current record holder. The so-called top quark will also be six times heavier than the Higgs boson and about 800 times heavier than the proton.

At present, the scientists are happy and have not yet decided to announce this discovery. It turns out that the results collected in the detector are just a coincidence-a simple fluctuation. They also need to collect data for several months-before figuring out how to interpret these interesting data correctly.

A participant in the CERN CMS experiment, Dr. Maciej Górski from the Participantwierk National Nuclear Research Center, told CERN what it actually observed in an interview with PAP.

New particles discovered from the release

“In the Large Hadron Collider accelerator, accelerated protons collide. Last year, the energy of these collisions reached 13 TeV (teraelectron volts). Therefore, it can be said that if all such energy is converted into mass, according to the equation E = mc ^ 2, during the collision of two protons, we can produce about 7,000. Proton-antiproton pairs “-Compare Dr. Gorsky.

In such a high-energy interaction, particles that cannot be obtained in other experiments are produced. These particles quickly decompose into other particles, are more friendly and well-known to scientists, and are recorded in the detector of the Large Hadron Collider. This is also the starting point of “reverse engineering”: physicists try to reconstruct what might have happened before the collision from the traces of the collision.

For example, scientists are looking for events that might cause a high-quality particle and then decay it into only two high-energy photons. Then, it is relatively easy to infer the mass of the decay particle.

Dr. Gorski said that the scientists mapped the mass of this continuous “reconstructed” particle on a picture. If nothing particularly interesting happens in the experiment, the graph is smooth (due to statistical laws). However, if any anomalous particles are formed in the collision, “humps” will appear in the graph.

In the ATLAS and CMS experiments, a peak appeared with a mass of 750 GeV. “These experiments show that there is a certain excess in the mass distribution of the two photons,” said Dr. Gorsky.

Is the foot a foot or is the foot non-footed?

“It feels that we have discovered something completely new and there is still a long way to go. For now, the results collected this year and last year are on the verge of being considered a new effect. However, these signs indicate that there may be some Interesting things, worth a look. He admitted waiting for more results. Then you may find that the “humps” on the graph will disappear and be overwhelmed by background noise. If there are new particles, please rest assured that the hump will still exist.

The current model suggests that the new heavy particles (if any) are bosons and therefore have interacting particle types. Dr. Gorsky speculates that this effect may be so weak that it has not yet been studied.

Researchers also do not rule out that the new particle may be the first of the new high-quality particles. The scientist said: “The trouble may be that the next particle in this class may be too heavy for us to even observe it on the Large Hadron Collider.” However, he firmly insisted on the view that there is no point in the existence of sentient beings. : First of all, it must be confirmed whether this new large particle exists at all.

Update on August 11, 2016:
However, the results of the Large Hadron Collider (LHC) at CERN may indicate that new supermassive particles with a mass of about 750 GeV have been observed, but they have not been confirmed. The recorded results proved to be statistical fluctuations-announced in August 2016 at the ICHEP 2016 conference in Chicago.
