    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 root s = 7 TeV collected by the CMS
detector at the LHC. The data sample used corresponds to an integrated
luminosity of 34 pb(-1). 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."
