The Higgs sector of the minimal SUSY $B-L$ model | | Lorenzo Basso
; | | Date: |
21 Apr 2015 | | Abstract: | 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, that 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,
even though recent data disfavour it, the enhancement of the Higgs-to-diphoton
coupling will be described to show model features beyond the MSSM. | | Source: | arXiv, 1504.5328 | | Services: | Forum | Review | PDF | Favorites | |
