Abstract
We have searched for second-generation leptoquark (LQ) pairs in the mu mu + jets channel using 94 +/- 5 pb(-1) of (p) over bar p collider data collected by the DO experiment at the Fermilab Tevatron during 1993-1996. No evidence for a signal is observed. These results are combined with those from the mu v + jets and vv + jets channels to obtain 95% confidence level (C.L.) upper limits on the LQ pair production cross section as a function of mass and beta, the branching fraction of a LQ decay into a charged lepton and a quark. Lower limits of 200(180) GeV/c(2) for beta = 1(1/2) are set at the 95% C.L. on the mass of scalar LQ. Mass limits are also set on vector leptoquarks as a function of beta.
