The lower mass limit on the lightest supersymmetric particle, using ALEPH data up to 188.6 GeV

The lightest srpersymmetric particle (LSP) is expected to be stable, massive and neutral. Direct searches for supersymmetric particles in the context of the minimal supersymmetric extension to the standard model have been performed with the ALEPH detector. Using about 175pb-1 of data with centre-of-...

Sumario:The lightest srpersymmetric particle (LSP) is expected to be stable, massive and neutral. Direct searches for supersymmetric particles in the context of the minimal supersymmetric extension to the standard model have been performed with the ALEPH detector. Using about 175pb-1 of data with centre-of-mass energies near 189GeV a limit on the mass of the LSP of M_LSP>32.3GeV/c2 at 95% confidence can be derived, assuming R-parity is conserved.
