We present the results of a search for third generation leptoquark (LQ) pairs in 110 +/- 8 pb(-1) of (p) over bar p collisions at root s = 1.8 TeV recorded by the Collider Detector at Fermilab. We assume third generation leptoquarks decay to a tau lepton and a b quark with branching ratio beta. We observe one candidate event, consistent with standard model background expectations. We place upper limits on sigma((p) over bar p --> LQ(<(LQ)over bar>).beta(2) as a function of the leptoquark mass M(LQ). We exclude at 95% confidence level scalar leptoquarks with M(LQ) < 99 GeV/c(2), gauge vector leptoquarks with M(LQ) < 225 GeV/c(2), and nongauge vector leptoquarks with M(LQ) < 170 GeV/c(2) for beta = 1.

Abstract

We present the results of a search for third generation leptoquark (LQ) pairs in 110 +/- 8 pb(-1) of (p) over bar p collisions at root s = 1.8 TeV recorded by the Collider Detector at Fermilab. We assume third generation leptoquarks decay to a tau lepton and a b quark with branching ratio beta. We observe one candidate event, consistent with standard model background expectations. We place upper limits on sigma((p) over bar p --> LQ(<(LQ)over bar>).beta(2) as a function of the leptoquark mass M(LQ). We exclude at 95% confidence level scalar leptoquarks with M(LQ) < 99 GeV/c(2), gauge vector leptoquarks with M(LQ) < 225 GeV/c(2), and nongauge vector leptoquarks with M(LQ) < 170 GeV/c(2) for beta = 1.
