Implications of Higgs to diphoton decay rate in the bilinear R-parity violating supersymmetric model

الأصل · EN

The Large Hadron Collider has recently discovered a Higgs-like particle having a mass around 125 GeV and also indicated that there is an enhancement in the Higgs to diphoton decay rate as compared to that in the standard model. We have studied implications of these discoveries in the bilinear R-parity violating supersymmetric model, whose main motivation is to explain the non-zero masses for neutrinos. The R-parity violating parameters in this model are ε and bε, and these parameters determine the scale of neutrino masses. If the enhancement in the Higgs to diphoton decay rate is true, then we have found ε 0.01 GeV and bε 1 GeV² in order to be compatible with the neutrino oscillation data. Also, in the above mentioned analysis, we can determine the soft masses of sleptons (mₗ) and CP-odd Higgs boson mass (mₐ). We have estimated that mₗ 300 GeV and mₐ 700 GeV. We have also commented on the allowed values of ε and bε, in case there is no enhancement in the Higgs to diphoton decay rate. Finally, we present a model to explain the smallness of ε and bε.
