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 MLQ. Assuming B=1 we exclude at the 95% confidence level third-generation scalar leptoquarks with MLQ<94GeV/c2 and third-generation vector leptoquarks with MLQ<216GeV/c2(MLQ<148GeV/c2) assuming Yang-Mills (anomalous) coupling.
