Abstract We study phenomenological aspects of supersymmetric SO (10) GUTs with sum rules among soft SUSY breaking parameters. In particular, the sum rule related to the stau mass leads to the constraints from the requirements of successful electroweak breaking and the positivity of stau mass squared. The bottom quark mass is also estimated.

TLDR
The gauge hierarchy achieved by a fine-tuning in the superpotential would be violated in general due to the nonuniversal SUSY-breaking terms, but it is preserved for a certain class of the soft terms derived from a [ital hidden] ansatz. Expand
