Query: QCD Phase Transition in a Strong Magnetic Background   We investigate the properties of the deconfining/chiral restoring transition
for two flavor QCD in presence of a uniform background magnetic field. We adopt
a standard staggered discretization of the fermion action 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 |e|B ~ 0.75 GeV^2. 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.
