Abstract

We report on a search for charge-1/3 third-generation leptoquarks (LQ) produced in p collisions at =1.96 TeV 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 (pLQ)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<229 GeV.
