We report on a search for second generation leptoquarks (LQ) produced in p[ovr p] collisions at [radical] (s) =1.8 TeV using the D0 detector at Fermilab. Second generation leptoquarks are assumed to be produced in pairs and to decay to either [mu] or [nu] and either a strange or a charm quark (q) . Limits are placed on [sigma](p[ovr p][r arrow] LQ[ovr LQ][r arrow][mu][nu]+jets) as a function of the mass of the leptoquark. For equal branching ratios to [mu]q and [nu]q , second generation scalar leptoquarks with a mass below 160 GeV/c[sup 2] , vector leptoquarks with anomalous minimal vector couplings with a mass below 240 GeV/c[sup 2] , and vector leptoquarks with Yang-Mills couplings with a mass below 290 GeV/c[sup 2] , are excluded at the 95[percent] confidence level.
