AbstractWe propose a supersymmetric explanation of the diphoton excess in the Minimal Supersymmetric Standard Model (MSSM) with the leptonic R-parity violation. In our model, sneutrino serves as the 750 GeV resonance and produced through quark-antiquark annihilation. With introducing appropriate trilinear soft parameters, we show that the diphoton branching ratio is significantly enhanced compared with the conventional MSSM. For current dijet and W-pair LHC constraints, we can successfully fit the observed diphoton signal rate in sizeable parameter regions, the resulting parameter space strongly favor the masses of light smuon and stau within the range from 375-500 GeV, which depends on the choice of electroweakino masses and soft trilinear terms. While after taking into account the compatibility of diphoton excess between the 8 TeV and 13 TeV LHC, only the coupling involved with the second generation quarks is survived. In this case, the corresponding parameter space favors a narrow mass range of smuon and stau with m (mu) over tilde (1) (T) over tilde (1) is an element of [375; 390] GeV. Even if the 750 GeV diphoton excesses were not con fi rmed by the ATLAS and CMS experiments, we point out that our proposal can still be used to explain the current and future tentative diphoton excesses.
