  The observation of an evaporating black hole would provide definitive
information on the elementary particles present in nature. In particular, it
could discover or exclude particles beyond those present in the standard model
of particle physics. We consider a wide range of motivated scenarios beyond the
standard model and identify those which would be best probed in the event of an
observation. For those models we define representative benchmark parameters and
characterise the photon spectra as a function of time. For the supersymmetric
benchmark model, where most of the new particles produce secondary photons, we
provide secondary spectra and discuss the subtle interplay between faster black
hole evaporation and an increased flux of secondary photons. Finally, we
discuss the impact of these models on future experimental analysis strategies.
