摘要：

We study the sensitivity of the Tevatron and the 7 TeV LHC to a leptoquark S coupling to a top quark and a charged lepton L (= e, mu, or tau). For the Tevatron, we focus on the case m(S) < m(t), where the leptoquark pair production cross section is large, and the decay is three-body: S -> WbL(+/-). We argue that existing Tevatron observations could exclude m(S) less than or similar to 160 GeV. For m(S) > m(t), we show that the LHC experiments with low integrated luminosity could be sensitive to such leptoquarks decaying to tl(+/-) with l = mu or tau.
