Abstract

We present the results of a search for third generation leptoquark (LQ) pairs in 110±8pb^ࢤ1of p^¯p collisions at √s=1.8TeV recorded by the Collider Detector at Fermilab. We assume third generation leptoquarks decay to a Τ lepton and a bquark with brancing ratio β. We observe one candidate event, consistent with standard model background expectations. We place upper limits on σ(p^¯p→LQLQ^¯)β² as a function of the leptoquark mass M_LQ. We exclude at 95% confidence level scalar leptoquarks with M_LQ<99GeV/c², gauge vector leptoquarks with MLQ<225GeV/c², and nongauge vector leptoquarks with M_LQ<170GeV/c² for β=1.
