For the first time, tones formed from photons during proton collisions were observed

CERN announced this For the first time, during the collision of protons, it became possible to observe how two tona are created from two photons. The research was possible thanks to the exceptional resolution of the CMS detector. At the same time, he made the most precise measurements of the tuna's anomalous magnetic moment.

Tau belongs to the leptons, which – along with quarks – create matter. This particle was discovered in the late 1970s, and the associated neutrino, the tau neutrino, was discovered in 2000. Tau neutrinos are difficult to study because they remain stable for only 290×10.-15 Seconds. The remaining two negatively charged leptons are much better studied: the electron and the muon. We understand their magnetic moments and anomalous magnetic moments very well. In fact, the electron's anomalous magnetic moment is one of the best understood properties in particle physics. It is fully consistent with the standard model. In contrast, the muon's anomalous magnetic moment is one of its most intensively studied properties.
In the case of tau, due to its very short lifetime, studying this feature is difficult. The measurements made so far have a very large error.

While researching accelerators, scientists look for traces of a unique process during which two photons interact and, as a result, two tautomers appear. They then decay into muons and charged electrons or pions and neutrinos. So far, ATLAS and CMS experiments have observed such a phenomenon during lead nuclei collisions. Now the first observation of proton collisions has been made. We were able to isolate this incident from others. “This unique achievement will enable many pioneering measurements to be carried out,” says Michael Pitt from the CMS analyst team.

Immediately after observing the event they were looking for, scientists made the most precise measurements of the tuna's anomalous magnetic moment. The accuracy of the measurement will certainly be improved in the future, but the current achievement demonstrates the importance of what has been achieved in the field of particle physics. Compared with previous measurements, the margin of error has been reduced by up to 7 times. It is truly exciting that we can finally come close to defining the basic properties of the Tao“, says Isaac Neuteling from the CMS analyst team. His colleague Xuelong Quin adds that it took more than 20 years to improve the accuracy of the measurements.
