Title:     Relatively Heavy Higgs Boson in More Generic Gauge Mediation

Abstract: We discuss gauge mediation models where the doublet messengers and Higgs doublets 
are allowed to mix through a charged" coupling. The charged coupling replaces 
messenger parity as a means of suppressing flavor changing neutral currents
without introducing any unwanted CP violation. As a result of this mixing between
the Higgs doublets and the messengers, relatively large A-terms are generated at the
messenger scale. These large A-terms produce a distinct weak scale mass spectrum.
Particularly, we show that the lightest Higgs boson mass is enhanced and can be as
heavy as 125 GeV for a gluino mass as light as 2TeV. We also show that the stops
are heavier than that predicted by conventional gauge mediation models. It is also
shown that these models have a peculiar slepton mass spectrum.
