ICRR-590-2011-7 IPMU11-0116 Relatively Heavy Higgs Boson in More Generic Gauge Mediation

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 2 TeV. 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. ar X i
