Query: Hawking radiation for a Proca field in D dimensions II: charged field in
  a brane charged black hole   We generalise our first analysis of the wave equation for a massive vector
boson in the background of a D-dimensional Schwarzschild black hole, by adding
charge both to the field and the black hole, on the 3+1 dimensional Standard
Model brane. A detailed numerical study is performed to obtain the transmission
factor for the coupled (as well as decoupled) system of equations describing
the Proca field modes, varying the angular momentum number, mass, charge and
space-time dimensions. A qualitatively new feature arising from the
introduction of charge is the appearance of superradiant modes, which we
investigate. We then compute the Hawking fluxes, and analyse the effect of the
charge. In particular we observe an inverted charge splitting effect for small
energies and for two or more extra dimensions. For neutral fields, we compare
the emission of massive particles with spins up to one and also compare the
Proca bulk-to-brane ratio of energy emission, showing that, as for a scalar
field, most of the energy is emitted on the brane.
