Limits onR-parity violation from cosmic ray antiprotons
Copyright policy )Limits onR-parity violation from cosmic ray antiprotons
We constrain the hadronic R-parity violating couplings in extensions to the minimal supersymmetric standard model. These interactions violate baryon and lepton number, and allow the lightest superpartner (LSP) to decay into standard model particles. The observed flux of cosmic ray antiprotons places a strong bound on the lifetime of the LSP in models where the lifetime is longer than the age of the universe. We exclude 10^-18
