摘要：

We investigate the properties of the deconfining/chiral restoring transition for two flavor QCD in the presence of a uniform background magnetic field. We adopt standard staggered fermions and a lattice spacing of the order of 0.3 fm. We explore different values of the bare quark mass, corresponding to pion masses in the range 200-480 MeV, and magnetic fields up to vertical bar e vertical bar B similar to 0: 75 GeV2. The deconfinement and chiral symmetry restoration temperatures remain compatible with each other and rise very slightly (< 2% for our largest magnetic field) as a function of the magnetic field. On the other hand, the transition seems to become sharper as the magnetic field increases.
