Phys. Rev. D 63, 115001 (2001) [12 pages]Direct probes of R-parity-violating supersymmetric couplings via single-top-squark productionReceived 15 December 2000; published 16 April 2001 We study the s-channel production of a single top squark in hadron collisions through an R-parity-violating mechanism, examining in detail the case in which the squark decays through an R-parity-conserving process into a bottom quark, a lepton, and missing energy. We show that the top squark can be discovered if its mass is less than 400 GeV, or that the current bound on the size of the R-parity-violating couplings can be reduced by up to one order of magnitude with existing data and by two orders of magnitude at the forthcoming run II of the Fermilab Tevatron. © 2001 The American Physical Society URL:
