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 ffiffi
s p ¼ 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 2 as a function of the
leptoquark mass, and leptoquarks with masses below 394 GeV are excluded at a 95% confidence level for
¼ 1, where is the leptoquark branching fraction into a muon and a quark. These limits are the most
stringent to date
