Search for Pair Production of Second-Generation Scalar Leptoquarks in pp Collisions at √s=7 TeV
Authors (1 total): J. Rohlf
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 √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 β2 as a function of the leptoquark mass, and leptoquarks with masses below 394 GeV are excluded at a 95% confidence level for β=1, where β is the leptoquark branching fraction into a muon and a quark. These limits are the most stringent to date.
