  Using the MacGibbon-Webber model, the instantaneous photon (gamma-ray)
emission spectra from PBHs in the Standard Model and mSUGRA benchmark models
were investigated numerically. The point source and diffuse gamma-ray spectra
from PBHs were also found numerically. It was found that the instantaneous
photon flux from PBHs in mSUGRA benchmark models is generally less than
approximately four times greater than in the Standard Model. The point source
flux from a PBH in its final stages of emission will in mSUGRA benchmark models
both quantitatively and qualitatively differ from that in the Standard Model.
The dominant part of the diffuse gamma-ray flux should not be affected by any
supersymmetric particles. However, for PBHs with initial mass approximately in
the range [4x10^13 g, 1x10^14 g], the diffuse Standard Model flux at photon
energies E_0 > ~1 GeV will generally be less than roughly 50% greater than for
mSUGRA benchmark models. The results generally show good agreement with
previous works, although model differences give some disagreement. It is
concluded that it is unlikely that the effects found could be detected with the
upcoming gamma-ray satellite GLAST, due for launch in 2006. This Master's
Thesis also gives a review of PBH formation and emission, as well as some
cosmological consequences associated with PBHs. The concept of supersymmetry in
quantum mechanics and particle physics is also introduced.
