Effect of two-loop correction in the formation of quarka??gluon plasma droplet

摘要

The effect of two-loop correction in quarka??gluon plasma (QGP) droplet formation is studied by introducing the two-loop correction factor in the mean-field potential. The correction factor leads to the stability in the droplet formations of QGP at different parametrisation factors of the QGP fluid. This also shows that the gluon parameter factor shifts to a larger value from its earlier value of one-loop correction in attaining the stability of the droplets. The results show a decrease in the observable QGP droplet sizes which are found to be 1.5a??2.0 fm radii with the two-loop correction. It indicates that the dynamics of the QGP droplet and the stability of the droplet withthe two-loop correction factor can be controlled by the fluid parameter in the model.
