AbstractAbstract
[en] The breaking of R-parity allows the lightest supersymmetric particle (LSP) to decay, and we study the cosmological bounds on its mass and lifetime. These bounds can be translated into a lower limit on the neutrino mass when R-parity is broken by a nonzero scalar neutrino v.e.v., and into lower limits on the symmetry breaking parameters when R-parity is broken by explicit couplings in the lagrangian
