  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.
