Phenomenological constraints on SUSY SU(5) GUTs with nonuniversal gaugino masses
Phenomenological constraints on SUSY SU(5) GUTs with nonuniversal gaugino masses
We study phenomenological aspects of supersymmetric SU(5) grand unified theories with non-universal gaugino masses. For large tan beta, we investigate constraints from the requirement of successful electroweak symmetry breaking, the positivity of stau mass squared and the b to s gamma decay rate. In the allowed region, the nature of …
