The see-saw mechanism of neutrino mass generation, when incorporated insupersymmetric theories with supergravity mediated supersymmetry breaking,results in low-energy lepton-flavour violation arising from the softsupersymmetry breaking slepton masses. The parameter space of supergravitytheories with conserved R-parity is severely constrained by the requirementthat the LSP provide cold dark matter with a relic density in the rangeindicated by the recent WMAP measurements, as well as by laboratoryconstraints. We calculate the $\meg$ branching ratio for the constrainedminimal supersymmetric standard model, over the range of parameters consistentwith WMAP and laboratory constraints, in families of see-saw modelparameterizations which fit the low energy neutrino measurements. We find thatover much of the range of see-saw models, for supersymmetry parametersconsistent with WMAP and laboratory bounds, the resulting predicted rates for$\meg$ (and other charged lepton flavour violating processes) are withincurrent experimental limits, but that these rates should be detectable with thenext generation of lepton-flavour violation experiments.Comment: References added, minor typos correcte
