Search for third generation scalar leptoquarks in pp collisions at $ \sqrt{s}=7 $ TeV with the ATLAS detector

Abstract

AbstractA search for pair-produced third generation scalar leptoquarks is presented, using proton-proton collisions at$ \sqrt{s}=7 $TeV at the LHC. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 4.7 fb−1. Each leptoquark is assumed to decay to a tau lepton and ab-quark with a branching fraction equal to 100%. No statistically significant excess above the Standard Model expectation is observed. Third generation leptoquarks are therefore excluded at 95% confidence level for masses less than 534GeV.
