Abstract
A search for pair production of second-generation scalar leptoquarks in the final state with two muons and two jets is performed using proton-proton collision data at sqrt(s) = 7 TeV collected by the CMS detector at the LHC. The data sample used corresponds to an integrated luminosity of 34 inverse picobarns. The number of observed events is in good agreement with the predictions from the standard model processes. An upper limit is set on the second-generation leptoquark cross section times beta^2 as a function of the leptoquark mass, and leptoquarks with masses below 394 GeV are excluded at a 95% confidence level for beta = 1, where beta is the leptoquark branching fraction into a muon and a quark. These limits are the most stringent to date.

Summary
A and search for pair production of two jets is performed using second-generation scalar proton-proton collision dleaptatoqatuaprkffisffis1⁄4in7thTeefiVnaclosltlaetcetewditbhytwthoemCuMonSs detector at the LHC. An upper limit is set on the second-generation leptoquark cross section times 2 as a function of the leptoquark mass, and leptoquarks with masses below 394 GeV are excluded at a 95% confidence level for 1⁄4 1, where is the leptoquark branching fraction into a muon and a quark. We consider the decay of a second-generation leptoquark to a muon and a quark.
