摘要
We report on a search for pair production of first-generation scalar leptoquarks (LQ) in p (p) over bar collisions at root s=1.96 TeV using an integrated luminosity of 203 pb(-1) collected at the Fermilab Tevatron collider by the CDF experiment. We observe no evidence for LQ production in the topologies arising from LQ (LQ) over bar -> eqeq and LQ (LQ) over bar -> eq nu q, and derive 95% C.L. upper limits on the LQ production cross section. The results are combined with those obtained from a separately reported CDF search in the topology arising from LQLQ ->nu q nu q and 95% C.L. lower limits on the LQ mass as a function of beta=BR(LQ -> eq) are derived. The limits are 236, 205 and 145 GeV/c(2) for beta=1, beta=0.5 and beta=0.1, respectively.
