Is low energy supergravity consistent with cosmology and particle physics experiments?

Abstract

We construct a low energy supergravity model consistent with all cosmological and particle physics constraints, by omitting some of the usual simplifying assumptions in the hidden sector. The model has heavy squarks, light gluinos and a higgsino as the lightest supersymmetric particle. The experimental implications of the model are discussed. In particular, the possibility of detecting photinos in monojet events, and a new way of producing Higgs bosons in e+e- collisions with a good signature, H0 + missing energy, occur as new results.
