Description
We present a new mechanism to generate large A-terms at tree-level in the MSSM
through the use of superpotential operators. The mechanism trivially resolves the
A/m^2 problem which plagues models with conventional, loop-induced A-terms. We
study both MFV and non-MFV models; in the former, naturalness motivates us to
construct a UV completion using Seiberg duality. Finally, we study the phenomenology
of these models when they are coupled to minimal gauge mediation. We find that after
imposing the Higgs mass constraint, they are largely out of reach of LHC Run I, but
they will be probed at Run II. Their fine tuning is basically the minimum possible in
the MSSM.
