Split supersymmetry under GUT and current dark matter constraints
We recalculate the two-loop beta functions for three gauge couplings taking into account all low energy threshold corrections in split supersymmetry (split-SUSY) which assumes a very high scalar mass scale $$M_S$$ . We find that in split-SUSY with a gaugino mass unification assumption and with a large $$M_S$$ the gauge …
