Semi-Direct Gauge Mediation with the 4-1 Model

Understand

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 SUSY-breaking F-terms induce D-terms from which SUSY-split messenger masses arise.
• We calculate these masses by three complementary methods.
• Additionally, we compute the one-loop corrections to the masses.
