Description

We present a general analysis of the contraints derived from neutrino physics on explicit R-parity breaking in supersymmetric models. We consider bounds coming from (i) neutrino oscillations, (ii) neutrinoless double beta decay and (iii) neutrino cosmology and astrophysics. Our bounds are more stringent than the previous limits, in particular for lepton number violation involving the third generation. In several cases we obtain tight bounds on R-violating couplings which previously have been unconstrained. (orig.)
