Description
Non-universal boundary conditions in grand unified theories can lead
to non-universal gaugino masses at the unification scale. In R-parity
preserving theories the lightest supersymmetric particle is a natural
candidate for the dark matter. We have studied the composition of the
lightest neutralino in non-universal gaugino mass cases from the
SU(5), and implications on the dark matter. In the 24 dimensional
representation areas of proper thermal relic density are found. The
possibility to observe the neutral MSSM Higgs bosons (h/H/A) at the LHC
via neutralino cascades when the lightest neutralino is dark matter, is
discussed, and the connection to neutralino dark matter is
established.
