“…This is compatible with the Standard Model prediction (3.56±0.18)×10 −9 [75]. In R-parity violating models there are several new sources for this reaction both at tree-level and at one-loop level and the limits on R-parity violating couplings have been analyzed [76,77]. The most stringent bounds on the products of two trilinear couplings are of the order of 3 · 10 −11 × m 2 ν , where the masses are given in GeV's.…”

R-parity violation modifies the phenomenology of supersymmetric models considerably. We study a version of NMSSM, which contains right-handed neutrinos and in which spontaneous R-parity violation is possible. We study the ensuing effects of spontaneous breaking to the Higgs decay modes, taking into account the measured mass of the Higgs boson and experimental constraints, including rare decays. We find that a possible light scalar, dominantly a sneutrino, helps to increase the Standard Model (SM) Higgs-like scalar mass to the measured value. At the same time, a lighter stop than in the MSSM is allowed. The Higgs decay rates in the studied model can somewhat differ from the SM expectations, although the most prominent difference is a universal suppression in the couplings due to the mixing of doublet scalars with singlets. The charged, pseudoscalar, and other than the two lightest scalar Higgses are typically heavier than 1 TeV in the parameter region where R-parity is spontaneously broken.
