Including non-holomorphic soft terms in the RGE running of GMSB with adjoint messengers enlarges the allowed parameter space, keeps the stau non-tachyonic at small hypercharge messenger coupling, and can reduce SUSY contributions to muon g-2 by up to about 50 x 10^-10.

abstract
In the MSSM the quasi-infra-red fixed point for the top-quark Yukawa coupling gives rise to specific predictions for the soft-breaking parameters. We discuss the extent to which these predictions are modified by the introduction of additional ``non-holomorphic'' soft-breaking terms. We also show that in a specific class of theories there exists an RG-invariant trajectory for the ``non-holomorphic'' terms, which can be understood using a holomorphic spurion term.

Non-holomorphic Contributions in GMSB with Adjoint Messengers
Including non-holomorphic soft terms in the RGE running of GMSB with adjoint messengers enlarges the allowed parameter space, keeps the stau non-tachyonic at small hypercharge messenger coupling, and can reduce SUSY contributions to muon g-2 by up to about 50 x 10^-10.
