New particle discovered at the Large Hadron Collider

Physicists have discovered a new particle - a double charmed tetraquark Tcc +. This is reported on the official

website of the European Organization for Nuclear Research (CERN).

Today LHCb is the smallest offour main detectors at the LHC collider in the European organization for nuclear research CERN in Geneva. The experiment is carried out to study the asymmetry of matter and antimatter in b-quark interactions.

CERN reports that the Tcc + tetraquark is the onlya particle known to science, which consists of four quarks. The peculiarity of this particle is that two quarks are charmed or c-quarks. At the same time, charmed antiquarks are absent in it.

C-quark or charmed quark - quark with charge+ e, which belongs to the second generation. With a mass of 1.25 GeV, it ranks third in mass among quarks. Scientists predicted its appearance back in 1970.

In particle physics, charmcalled aroma. This is a quantum number that characterizes the type of quark. There are six of them in total. CERN noted that the new tetraquark can be called a long-liver. The fact is that its lifetime is 10 to 500 times longer than that of particles with the same mass.
