Search for scalar top quark production in in ⊯ pp collisions at ⊡ s = 1.8 TeV

Journal Article

We have searched for direct production of scalar top quarks at the Collider Detector at Fermilab in 88pb-1of p⊯p collisions at vs=1.8TeV. We assume the scalar top quark decays into either a bottom quark and a chargino or a bottom quark, a lepton, and a scalar neutrino. The event signature for both decay scenarios is a lepton, missing transverse energy, and at least two b-quark jets. For a chargino mass of 90GeV/c2and scalar neutrino masses of at least 40GeV/c2, we find no evidence for scalar top production and present upper limits on the production cross section in both decay scenarios. © 2000 The American Physical Society.
