Query: Magnetic Field Effect on Charged Scalar Pair Creation at Finite
  Temperature   In this work we explore the effects of a weak magnetic field and a thermal
bath on the decay process of a neutral scalar boson into two charged scalar
bosons. Our findings indicate that magnetic field inhibits while temperature
enhances the pair production. The employed formalism allows us to isolate the
contribution of magnetic fields in vacuum, leading to a separate analysis of
the effects of different ingredients. This is essential since the analytical
computation of the decay width necessarily needs of some approximation and the
results that can be found in the literature are not always coincident. We
perform the calculation in vacuum by two different weak field approximations.
The particle pair production in vacuum was found to coincide with finite
temperature behavior, which is opposite to results obtained by other authors in
scenarios that involve neutral particles decaying into a pair of charged
fermions. Among other differences between these scenarios, we traced that the
analytical structure of the self-energy imposed by the spin of particles
involved in the process is determinant in the behavior of the decay rate with
the magnetic field.
