Description
We study gaugino mass generation in the context of semi-direct gauge
mediation models, where the messengers are charged under both the hidden
sector and the standard model gauge groups while they do not play
important roles in dynamical supersymmetry breaking. We clarify the
cancellation of the leading contributions of the supersymmetry breaking
effects to the gaugino mass in this class of models in terms of the
macroscopic effective theory of the hidden sector dynamics. We also
consider how to retrofit the model so that we obtain the non-vanishing
leading contribution to the gaugino mass.
