Description
We study the implications of non-universal boundary conditions for the composition
of the lightest neutralino as well as for the upper bound on its mass in
supersymmetric grand unified theories. We derive sum rules for neutralino and
chargino masses in different representations of the simplest grand unified theory
based on SU(5) which lead to different non-universal boundary conditions for the
gaugino masses at the unification scale. We then consider implications of the
non-universal gaugino masses, that arise in such a grand unified theory, for the
phenomenology of Higgs bosons. In particular we investigate the detection of heavy
neutral Higgs bosons H0, A0 in the decay H0, A0 -> Chi2^0 Chi2^0 to 4l. We also study
the possibility of detecting the neutral Higgs bosons in cascade decays Chi2^0 -> h0
(H0, A0) Chi1^0 -> b bbar Chi1^0.
