Search for second-generation scalar leptoquarks in p anti-p collisions at s**(1/2) = 1.96-TeV

Results on a search for pair productionof second generation scalar leptoquarkin p{bar p} collisions at {radical}s=1.96 TeV are reported. The data analyzed were collected by the CDF detector during the 2002-2003 TevatronRun II and correspond to an integrated luminosity of 198 pb{sup -1}. Leptoquarks(LQ) are sought through their decay into (charged) leptons and quarks, with final state signatures represented by two muonsand jets and one muon, large transverse missing energyand jets. We observe no evidence for LQ production and derive 95% C.L. upper limits on the LQ production cross sections as well as lower limits on their mass as a function of {beta}, where {beta} is the branching fractionfor LQ {yields} {mu}q.
