In experimental studies of quark-gluon plasma at accelerators, charmonium and bottomonium play an important role, since their onset dissociation is one the few signs a phase transition in hot superdense medium. These particles represent bound states heavy quark antiquark charm bottom flavour, respectively. One well-studied research methods considered to be phenomenological models, where interac...

When nuclear matter is heated beyond 2 trillion degrees, it becomes a strongly coupled plasma of quarks and gluons. Experiments using highly energetic collisions between heavy nuclei have revealed that this new state of matter is a nearly ideal, highly opaque liquid. A description based on string theory and black holes in five dimensions has made the quark-gluon plasma an archetypical strongly ...

The temperature and chemical potential dependent surface tension of bags is introduced into the gas of quark-gluon bags model. The suggested model is solved analytically. It resolves a long standing problem of a unified description of the first and second order phase transition with the cross-over. Such an approach is necessary to model the complicated properties of quark-gluon plasma and hadro...
