Leptophobic $Z^\prime$ bosons in the secluded UMSSM

Understand

We perform a comprehensive analysis of the secluded UMSSM model, consistent with present experimental constraints.

• We find that in this model the additional $Z^\prime$ gauge boson can be leptophobic without resorting to gauge kinetic mixing and, consequently, also $d$-quark-phobic, thus lowering the LHC bounds on its mass.
• The model can accommodate very light singlinos as DM candidates, consistent with present day cosmological and collider constraints.
• Light charginos and neutralinos are responsible for muon anomalous magnetic predictions within 1$\sigma$ of the measured experimental value.
