Search for the lightest scalar top quark in events with two leptons in pp‾ collisions at √s=1.96 TeV

Abstract

Data collected by the DO detector at a pp‾ center-of-mass energy of 1.96 TeV at the Fermilab Tevatron Collider have been used to search for pair production of the lightest supersymmetric partner of the top quark decaying into bev. The search is performed in the ll'=eμ and μ μ final states. No evidence for this process has been found in data samples of approximately 400 pb^-1. The domain in the [M(t^~₁), M (τ^~)] plane excluded at the 95% C.L. is substantially extended by this search.
