Interpreting $750$ GeV Diphoton Excess with R-parity Violating Supersymmetry
Abstract
We propose an supersymmetric explanation of the diphoton excess in the Minimal Supersymmetric Standard Model with the leptonic R-parity violation. Where the sneutrino serves as the 750 GeV resonance and produced through quark anti-quark annihilation. With introducing appropriate trilinear soft parameters, we show that the diphoton branching ratio is significantly enhanced compared with the conventional MSSM. The parameter space favored by diphoton excess strongly indicates the mass of smuon and stau fall into the range (375-480) GeV, which depending on the electroweakino masses. In addition, the -parity-violating trilinear couplings involved with second generation quarks are both favored by compatibility of diphoton excess and low-energy constraints.
