摘要：

We report on a search for second generation scalar leptoquarks with the DO detector at the Fermilab Tevatron <p(p)over bar> collider at root s = 1.8 TeV. This search is based on 12.7 pb(-1) of data. Second generation leptoquarks are assumed to be produced in pairs and to decay into a muon and quark with branching ratio beta or into a neutrino and quark with branching ratio 1 - beta. We obtain cross section times branching ratio limits as a function of leptoquark mass and set lower limits on the leptoquark mass at the 95% confidence level.
