Cornell potential in collisional quark-gluon plasma

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 interaction between quarks described by Cornell-type potentials, as well its modifications. This article examines influence movement environment on potential, using dynamic screening. For screening, dielectric function wake field has been used analogy with electrodynamics ordinary plasma, view similarity description, which characteristic only for these states. obtained from collisional based Boltzmann equation Bhatnagar-Gross-Krook collision operator. As consequence, describes medium rarefied gas pair collisions particles. Effective potentials given are constructed method random-phase approximation. Potentials were relative motion frequency counterpropagating The changes potential direction particle graphically shown, depending magnitude parameters.
