A further example is given by the decays of excited states of charmonium (bound state of charm quark and antiquark).

To prove the existence of this plasma and study its properties, the physicists' approach consists in tracking down rare particles in their detectors, composed of a charm quark and its antiquark (c-cbar pairs): the J/ψ meson.

One of its studies deals with “charmed particles,” which contain a charm or anticharm quark.

Important studies deal with “charmed particles”, which contain a charm or anticharm quark.

Theorists expect this force to fall off because the surrounding swarm of light quarks and gluons will tend to screen the charm quark and antiquark from each other, leading to less J/psi production.

The charm quark is one of the six quarks, the others being :

Since the D meson is the lightest meson containing a charm quark, it must change the charm quark into another quark to decay.

We consider in particular neutrinos from charm quark production.

Meson D is made of a quark charm and an antiquark up.
