Gravitational Back Reaction of Hawking modes
D. Ring
The radiation rate of an evaporating black hole is calculated in a toy model in which the geometry outside the collapsing matter is described by a Vaidya metric. When back reaction…
Neutrino Oscillations from Dirac and Majorana Masses
D. Ring
We present a scenario of neutrino masses and mixing angles. Each generation includes a sterile right handed neutrino in addition to the usual left handed one. We assume a hierarchy…
Gravitational GUT Breaking and the GUT-Planck Hierarchy
S. Urano, D. Ring, R. Arnowitt
It is shown that non-renormalizable gravitational interactions in the Higgs sector of supersymmetric grand unified theories (GUT's) can produce the breaking of the unifying gauge g…
Planck Scale Physics and the Testability of SU(5) Supergravity GUT
D. Ring, S. Urano, R. Arnowitt
GUT scale threshold corrections in minimal SU(5) supergravity grand unification are discussed. It is shown that predictions may be made despite uncertainties associated with the hi…
