Viscosity of quark-gluon plasma and gravitons Bose-Einstein condensate
We propose a theoretical model of quark-gluon plasma (QGP) produced at the Brookhaven National Laboratory (BNL) Relativistic Heavy Ion Collider (RHIC). In this model, we hypothesize that the gas of quarks and gluons are confined within the film of gravitons as a Bose-Einstein condensate (BEC) during the production of QGP. The structure of this theoretical model of QGP explains why QGP behaves in a liquid-like manner, resembling a perfect fluid rather than a gas. Based on this theoretical model, we calculated the shear viscosity of QGP. This is essentially the shear viscosity of the BEC film of gravitons. The computational results obtained in this study appear to be consistent with experimental findings.
