Semi-direct Gauge Mediation
Nathan Seiberg, Tomer Volansky, and Brian Wecht
TL;DR
This paper introduces a semi-direct gauge mediation framework where messengers are charged under the hidden sector gauge group but do not break supersymmetry, bridging the gap between ordinary and direct mediation methods.
Contribution
It proposes a new semi-direct gauge mediation approach and demonstrates its implementation using the 3-2 model with added massive SU(2) doublet messengers.
Findings
The framework effectively mediates supersymmetry breaking.
The phenomenology of the scenario is briefly discussed.
The approach offers a hybrid between existing mediation models.
Abstract
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 supersymmetry. From this point of view, our framework is between ordinary gauge mediation and direct mediation. As an example, we consider the 3-2 model of dynamical supersymmetry breaking, and add to it massive messengers which are SU(2) doublets. We briefly discuss the phenomenology of this scenario.
