Deconfinement transition in the revolving bag model

Based on the bag model , we revisit the deconfinement phase transition under rotation. On top of the usual rotational energy for noninteracting particles, we perturbatively analyze the revolution effect of the hadron bag, i.e., of the potential confining quarks. The revolution effect can be phenomenologically translated into the rotational correction to the QCD vacuum ener g y or the gluon condensate. We demonstrate that i f the revolution effect is (is not ) taken into account, the transition temperatu r e increases (decreases) as the angular velocit y increased. The 'revolving bag model ' provides a feasible explanation of the recent lattice simulations showing, contrary to effective models, that rotation favors the confined phase.

Automated summary

Based on the bag model, this study revisits the deconfinement phase transition under rotation. It is found that the transition temperature increases with increasing angular velocity when considering the revolution effect of the quarks in the bag, providing a reasonable explanation for recent lattice simulations.
