Abstract

We report on a search for the pair production of second generation scalar leptoquarks (LQ2) in pp¯ collisions at the center-of-mass energy s=1.96 TeV, using data corresponding to an integrated luminosity of 294±19 pb−1 recorded with the DØ detector. No evidence for a leptoquark signal in the LQ2LQ¯2→μqμq channel has been observed, and upper bounds on the product of cross section times branching fraction were set. This yields lower mass limits of mLQ2>247 GeV/c2 for β=B(LQ2→μq)=1 and mLQ2>182 GeV/c2 for β=1/2. Combining these limits with previous DØ results, the lower limits on the mass of a second generation scalar leptoquark are mLQ2>251 GeV/c2 and mLQ2>204 GeV/c2 for β=1 and β=1/2, respectively.
