Book excerpt: The authors report on a search for the pair production of second generation scalar leptoquarks (LQ2) in p{bar p} 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 D0 detector. No evidence for a leptoquark signal in the LQ2 {ovr LQ}2 → [mu]q[mu]q channel has been observed, and upper bounds on the product of cross section times branching fraction were set. This yields lower mass limits of m{sub LQ2} > 247 GeV for [beta] = [Beta](LQ{sub 2} → [mu]q) = 1 and m{sub LQ{sub 2}} > 182 GeV for [beta] = 1/2. Combining these limits with previous D0 results, the lower limits on the mass of a second generation scalar leptoquark are m{sub LQ{sub 2}} > 251 GeV and m{sub LQ{sub 2}} > 204 GeV for [beta] = 1 and [beta] = 1/2, respectively.
