Search for pair production of second generation scalar leptoquarks
Original language description
We report on a search for the pair production of second generation scalar leptoquarks (LQ) in p pbar collisions at the center of mass energy sqrt(s) = 1.96 TeV using a data set corresponding to an integrated luminosity of 1.0 fb-1 collected with the Ddiameter experiment at the Fermilab Tevatron Collider. Topologies arising from the LQLQbar -} muqnuq and LQLQbar -} muqmuq decay modes are investigated. No excess of data over the standard model prediction is observed and upper limits on the leptoquark pairproduction cross section are derived at the 95% C.L. as a function of the leptoquark mass and the branching fraction beta for the decay LQ -} muq. These are interpreted as lower limits on the leptoquark mass as a function of beta. For beta = 1 (0.5), scalar second generation leptoquarks with masses up to 316 GeV (270 GeV) are excluded.
