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

TL;DR

This paper explores a supersymmetric model with gauged baryon and lepton numbers, analyzing Higgs decay signals around 125 GeV to match experimental data from ATLAS and CMS.

Contribution

It introduces a supersymmetric extension with local gauge symmetries for baryon and lepton numbers and analyzes Higgs decay channels considering exotic quarks.

Findings

The model can naturally explain Higgs decay signals around 125 GeV.

It accounts for experimental Higgs data from ATLAS and CMS.

The analysis includes the impact of exotic quarks on decay channels.

Abstract

Assuming that the Yukawa couplings between the Higgs and exotic quarks cannot be ignored, we analyze the signals of decay channels $h\rightarrow\gamma\gamma$ and $h\rightarrow VV^*\;(V=Z,\;W)$ with the Higgs mass around $125\;{\rm GeV}$ 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.
