Search for second generation leptoquarks in pp-bar collisions at sqrt s=1.8 TeV. uri icon

abstract

  • We present the results of a search for second generation leptoquarks S2 using 19.3 pb-1 of data collected at the Collider Detector at Fermilab (CDF) in pp collisions at s=1.8 TeV during the 1992 93 collider run. We have searched for S2S2 pairs assuming that each leptoquark decays to a muon + quark with a branching ratio. We find two candidate events, consistent with an expected background of 1.11 0.48. We obtain upper limits on (pp S2S2) 2 as a function of MS2. Using a Monte Carlo prediction for S2S2 pair production, we exclude MS2<131GeV/c2 for =1 and MS2<96GeV/c2 for =0.5 at 95% C.L. 1995 The American Physical Society.
