Di-photon Excess Explained by a Resonant Sneutrino in R-parity Violating Supersymmetry

Abstract

We explain the recent excess seen by ATLAS and CMS experiments at around 750 GeV in the di-photon invariant mass as a narrow width sneutrino decaying to di-photons via a stau loop in R-parity violating Supersymmetry. The stau mass is predicted to be somewhere between half the resonant sneutrino mass and half the sneutrino mass plus 14 GeV. The scenario also predicts further signal channels at an invariant mass of 750 GeV, the most promising being into di-jets and $WW$. We also predict a left handed charged slepton decaying into $WZ$ and $W\gamma$ at a mass 750-754 GeV.

Added more discussion on WW, version accepted in PRD, 11 pages, 5 figures
