Abstract:
The relativistic rotation changes a critical temperature in QCD. Plenty of studies within various phenomenological and effective models predict decreasing of the critical temperature due to the rotation. At the same time, it follows from the lattice results for pure SU(3)-gluodynamics, that the critical temperature increases. But the rotation acts on both gluonic and fermionic degrees of freedom, and a combination of these effects may lead to unexpected results. In this report, the first lattice results for rotating QCD with dynamical fermions are presented. The results indicate, that effect of the rotation on fermions is opposite to gluons: it leads to the decrease of the critical temperature.
