Deconfinement in the presence of a strong magnetic background: an
exercise within the MIT bag model
   [PDF]

Eduardo S. Fraga, Leticia F. Palhares
We study the effect of a very strong homogeneous magnetic field B on the
thermal deconfinement transition within the simplest phenomenological approach:
the MIT bag pressure for the quark-gluon plasma and a gas of pions for the
hadronic sector. Even though the model is known to be crude in numerical
precision and misses the correct nature of the (crossover) transition, it
provides a simple setup for the discussion of some subtleties of vacuum and
thermal contributions in each phase, and should provide a reasonable
qualitative description of the critical temperature in the presence of B. We
find that the critical temperature decreases.
