N2 - We report on a search for second generation leptoquarks (LQ2) which decay into a muon plus quark in pp¯ collisions at a center-of-mass energy of
√s = 1.96 TeV in the D0 detector using an integrated luminosity of about 300 pb−1. No evidence for a leptoquark signal is observed and an upper
bound on the product of the cross section for single leptoquark production times branching fraction β into a quark and a muon was determined for
second generation scalar leptoquarks as a function of the leptoquark mass. This result has been combined with a previously published D0 search
for leptoquark pair production to obtain leptoquark mass limits as a function of the leptoquark–muon–quark coupling, λ. Assuming λ = 1, lower
limits on the mass of a second generation scalar leptoquark coupling to a u quark and a muon are mLQ2 > 274 GeV and mLQ2 > 226 GeV for
β = 1 and β = 1/2, respectively
