A Bayesian MCMC fit to neutrino, Higgs, and flavor data constrains the trilinear R-parity-violating couplings λ_i33 and λ'_i33 to at most ~10^-4, with tanβ below 15, in bino- and stop-LSP supersymmetric scenarios.

abstract
We investigate the implications of $R$-Parity violation (RPV) for quark flavour violation both by constraining the sneutrino masses to be positive and by studying the processes $b\to s\gamma$ and $K^0-\bar K^0$ mixing. In the latter there are two major contributions, one from ``direct'' one loop diagrams involving RPV couplings, and one from the ``indirect'' contributions generated by the renormalisation group. We compare the effects and discuss the implications of our results.

Markov Chain Monte Carlo analysis to probe trilinear $R$-parity violating SUSY scenarios and possible LHC signatures
A Bayesian MCMC fit to neutrino, Higgs, and flavor data constrains the trilinear R-parity-violating couplings λ_i33 and λ'_i33 to at most ~10^-4, with tanβ below 15, in bino- and stop-LSP supersymmetric scenarios.
