Search for pair production of second-generation scalar leptoquarks in pp collisions at √s=7TeV. Physical Review Letters, 106(20). doi:10.1103/PhysRevLett.106.2018030031-90071079-7114http://doi.org/10.1103/PhysRevLett.106.201803https://hdl.handle.net/11147/5026A 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=7TeV collected by the CMS detector at the LHC. The data sample used corresponds to an integrated luminosity of 34pb-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.© 2011 American Physical Society.eninfo:eu-repo/semantics/openAccessTellurium compoundsLeptoquarksPhotonsUpper limitsPair productionProton proton collisionsArticle2-s2.0-8487481368510.1103/PhysRevLett.106.20180310.1103/PhysRevLett.106.201803
