Collider phenomenology for supersymmetry with large tan beta

If the parameter tan beta of the minimal supersymmetric model is large, then b and tau Yukawa interactions are important. These can significantly modify the masses and decays of sparticles. We describe new calculations which allow a reliable exploration of large tan beta values, and discuss implications for collider experiments. For large values of tan beta, charginos and neutralinos may dominantly decay to tau leptons or b quarks. The usual cross sections for multilepton signatures may be greatly reduced, but supersymmetry may be detectable via new signals involving tau's or b's in the final state.
