Abstract

We report on a search for second generation leptoquarks (Phi(2)) using a data sample corresponding to an integrated luminosity of 110 pb(-1) collected at the Collider Detector at Fermilab. We present upper limits on the production cross section as a function of Phi(2) mass, assuming that the leptoquarks are produced in pairs and decay into a muon and a quark with branching ratio beta. Using a next-to-leading order quantum chromodynamics calculation, we extract a lower mass limit of M(Phi 2) > 202(160) GeV/c(2) at 95% confidence level for scalar leptoquarks with beta = 1(0.5).
