The Higgs Sector of the Minimal SUSY B - L Model

Abstract EN

I review the Higgs sector of the U ( 1 ) B - L extension of the minimal supersymmetric standard model (MSSM).

I will show that the gauge kinetic mixing plays a crucial role in the Higgs phenomenology.

Two light bosons are present, a MSSM-like one and a B - L -like one, which mix at one loop solely due to the gauge mixing.

After briefly looking at constraints from flavour observables, new decay channels involving right-handed (s)neutrinos are presented.

Finally, how model features pertaining to the gauge extension affect the model phenomenology, concerning the existence of R-Parity-conserving minima at loop level and the Higgs-to-diphoton coupling, will be reviewed.
