Abstract

We report on a search for charge-1/3 third-generation leptoquarks (LQ) produced in p¯p collisions at √s=1.8TeV using the D0 detector at Fermilab. Third-generation leptoquarks are assumed to be produced in pairs and to decay to a tau neutrino and a b quark with branching fraction B. We place upper limits on σ (p¯p→LQ¯LQ)B² as a function of the leptoquark mass M_LQ. Assuming B=1 we exclude at the 95% confidence level third-generation scalar leptoquarks with M_LQ<94GeV/c² and third-generation vector leptoquarks with M_LQ<216GeV/c²(M_LQ<148GeV/c²) assuming Yang-Mills (anomalous) coupling.
