Gauged baryon and lepton numbers in supersymmetry with a $125\mathrm{GeV}$ Higgs

Abstract

Assuming that the Yukawa couplings between the Higgs and exotic quarks cannot be ignored, we analyze the signals of decay channels $h\to \gamma \gamma$ and $h\to V{V}^{\ast }(V=Z,W)$ with the Higgs mass around $125\mathrm{GeV}$ in a supersymmetric extension of the standard model where baryon and lepton numbers are local gauge symmetries. Adopting some assumptions on relevant parameter space, we can account for the experimental data on Higgs from ATLAS and CMS naturally.
