Kinetic Mixing at Strong Coupling
Michele Del Zotto, Jonathan J. Heckman, Piyush Kumar +2
A common feature of many string-motivated particle physics models is additional strongly coupled U(1)'s. In such sectors, electric and magnetic states have comparable mass, and int…
The Higgs as a Probe of Supersymmetric Extra Sectors
Jonathan J. Heckman, Piyush Kumar, Brian Wecht
We present a general method for calculating the leading contributions to h -> gg and h -> gamma gamma in models where the Higgs weakly mixes with a nearly supersymmetric extra sect…
Comments on Gaugino Screening
Timothy Cohen, Anson Hook, Brian Wecht
Gauge mediated models of supersymmetry breaking often exhibit "gaugino screening," where to leading order in F, gaugino masses are unaffected by higher dimensional Kahler potential…
Electroweak Symmetry Breaking in the DSSM
Jonathan J. Heckman, Piyush Kumar, Cumrun Vafa +1
We study the theoretical and phenomenological consequences of modifying the Kahler potential of the MSSM two Higgs doublet sector. Such modifications naturally arise when the Higgs…
Semi-Direct Gauge Mediation with the 4-1 Model
Henriette Elvang, Brian Wecht
We analyze a model of Semi-Direct Gauge Mediation in which the hidden sector is the 4-1 model and the messenger fields are charged under the U(1) gauge group. At tree level, the SU…
Semi-direct Gauge Mediation
Nathan Seiberg, Tomer Volansky, Brian Wecht
We describe a framework for gauge mediation of supersymmetry breaking in which the messengers are charged under the hidden sector gauge group but do not play a role in breaking sup…
