Quark-hadron phase transition in a magnetic field

TL;DR

This paper investigates how magnetic fields influence the quark-hadron phase transition in QCD, revealing that magnetic fields lower the transition temperature and latent heat, and identifying a critical point where latent heat vanishes.

Contribution

It provides a detailed phase diagram of QCD in magnetic fields and identifies a critical point where the phase transition becomes second order.

Findings

Magnetic fields decrease the transition temperature and latent heat.

A phase diagram in temperature-magnetic field plane is constructed.

A critical point at T_* = 104 MeV and √(eH_*)=600 MeV is identified.

Abstract

Quark-hadron phase transition in QCD in the presence of magnetic field is studied. It is shown that both the temperature of a phase transition and latent heat decrease compared to the case of zero magnetic field. The phase diagram in the plane temperature--magnetic field is presented. Critical point, T_\ast=104 MeV, \sqrt{eH_\ast}=600 MeV, for which the latent heat goes to zero, is found.
