Description
The quark-hadron transition that happens in heavy ion collisions is likely influenced by the effects of rotation and magnetic field, both present due to the geometry of a generic non-head-on impact. The simultaneous imposition of these two phenomenological parameters would lead to a modification of the conventional phase diagram for QCD matter. We explore the deconfinement transition between quark-gluon plasma and hadron gas to map the continuous crossover region in a multi-dimensional domain spanned by baryon-chemical potential, external magnetic field and angular velocity as phase space coordinates. By utilizing a method involving the statistical hadronization model, the deconfinement temperature estimate is obtained and observed to decrease nearly monotonously along each of the axes, the drop being most pronounced when all three quasi-control parameters (collision energy and centrality dependent) take on high values. Some interesting implications of our novel results are outlined along with suggestive directions for further research.
