Abstract
We explore the consequences of the Higgs fields acting as messengers of su- persymmetry breaking. The hidden-sector paradigm in the gauge mediation framework is relaxed by allowing two types of gauge-invariant, renormalizable operators that are typi- cally discarded: direct coupling between the Higgses and supersymmetry breaking singlets, and Higgs-messenger mixing terms. The most important phenomenological consequence is a avor-dependent shift in sfermion masses. This is from a one-loop contribution, which we compute for a general set of weak doublet messengers. We also study a couple of ex- plicit models in detail, finding that precision electroweak constraints can be satisfied with a spectrum significantly difierent from that of gauge mediation.
