Description

We augment the conventional $T$-${\mu }_B$ planar phase
diagram for QCD matter by extending it to a multi-dimensional domain spanned by temperature $T$, baryon chemical potential ${\mu }_B$, external magnetic field $B$ and angular velocity $\omega$. This is relevant for peripheral heavy-ion collisions or astrophysical systems where $B$, $\omega$ are non-zero. Using two independent approaches, one from a rapid rise in entropy density and another dealing with a dip in the speed of sound, we identify deconfinement in the framework of a modified statistical hadronization model. We find that the deconfinement temperature $T_C({\mu }_B,\omega ,eB)$ decreases nearly monotonically with increasing ${\mu }_B,\omega$ and $eB$ with the most prominent drop (by nearly $40$ to $50$ MeV) in $T_C$ occurring when all the three quasi-control (collision energy and impact parameter dependent) parameters are tuned simultaneously to finite values that are achievable in present and upcoming heavy-ion colliders.
