Dark matter in gravity mediated supersymmetry breaking

摘要

In R parity conserving supersymmetric theories, the lightest superpartner (LSP) is stable. The LSPs may comprise a large fraction of the energy density of the current universe, which would lead to dramatic astrophysical consequences. In this talk, he discusses some of the main points they have learned about supersymmetric models from relic abundance considerations of the LSP.
