Update on Searches for Charginos and Neutralinos in e+e- Collisions at sqrt{s} up to 208 geV and Mass Limit for the Lightest Neutralino

Searches for pair production of charginos associated production of neutralinos have been performed using the data collected with the ALEPH detector in the year 2000 at sqrt{s} = 200-208GeV. This data sample corresponds to an integrated luminosity of ~217pb-`. No evidence for a signal has been observed. Assuming gaugino and sfermion mass unification and large sfermion masses, chargino pair production and neutralino associated production are excluded for masses close to the kinematic limit over large portions of the MSSM parameter space. In addition, a 95% CL lower limit of 39.6GeV/c2 has been set on the mass of the lightest neutralino for any tanBeta and m_0. This limit becomes 40.6GeV/c2 for any tanBeta and m_0 when negative results from Higgs searches are used, and 50GeV/c2 in minimal Supergravity models.
