Search for third generation leptoquarks in $$\bar{p}p$$ collisions at $$\sqrt{s} = 1.8$$ TeV
We present the results of a search for third generation leptoquark (LQ) pairs in 110±8pb-1of 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 b quark with branching ratio β. We observe one candidate event, consistent with standard model background expectations. We place upper limits on σ(p¯p→LQ$$\bar{LQ}$$)B2 as a function of the leptoquark mass MLQ. We exclude at 95% confidence level scalar leptoquarks with MLQ<99GeV/c2, gauge vector leptoquarks with MLQ<225GeV/c2, and nongauge vector leptoquarks with MLQ<170GeV/c2 for β=1.
