Search for the Associated Production of Chargino and Neutralino in Final States with Three Leptons involving Tau Leptons

Existing DO trilepton analyses with electrons and muons have been extended with searches for trilepton final states containing one or more tau leptons decaying hadronically. The searches use data taken with the DO detector at the Fermilab Tevatron ppbar collider at a center-of-mass energy of 1.96 TeV corresponding to an integrated luminosity of about 325 pb-1. The results constrain the associated production of charginos and neutralinos beyond the existing limits.
