QCD phase diagram in a magnetic background for different values of the pion mass

Abstract

We investigate the behavior of the pseudo-critical temperature of $N_f=2+1$ QCD as a function of a static magnetic background field for different values of the pion mass, going up to $m_{\pi }\simeq 660$ MeV. The study is performed by lattice QCD simulations, adopting a stout staggered discretization of the theory on lattices with $N_t=6$ slices in the Euclidean temporal direction; for each value of the pion mass the temperature is changed moving along a line of constant physics. We find that the decrease of $T_c$ as a function of $B$, which is observed for physical quark masses, persists in the whole explored mass range, even if the relative variation of $T_c$ appears to be a decreasing function of $m_{\pi }$, approaching zero in the quenched limit. The location of $T_c$ is based on the renormalized quark condensate and its susceptibility; determinations based on the Polyakov loop lead to compatible results. On the contrary, inverse magnetic catalysis, i.e. the decrease of the quark condensate as a function of $B$ in some temperature range around $T_c$, is not observed when the pion mass is high enough. That supports the idea that inverse magnetic catalysis might be a secondary phenomenon, while the modifications induced by the magnetic background on the gauge field distribution and on the confining properties of the medium could play a primary role in the whole range of pion masses
