摘要: A search for pair-production of first generation scalar leptoquarks is performed in the final state containing an electron, a neutrino, and at least two jets using proton-proton collision data sqrt(s)=7 TeV. The were collected by CMS detector LHC, corresponding to integrated luminosity 36 inverse picobarns. number observed events good agreement with predictions standard model processes. Prior results dielectron channel are combined this electron+neutrino search. 95% confidence level lower limit set on mass leptoquark 340 GeV beta=0.5, where beta branching fraction electron quark. These represent most stringent direct limits date values greater than 0.05.
