Abstract
- The most recent results from searches of leptoquark-like signatures are presented using 1.03 and 4.7 fb−1of pp collision data collected by the ATLAS detector with s=7 TeVand 19.6 fb−1of pp collision data collected by the CMS detector with s=8 TeVat the LHC. First- and second-generation scalar leptoquarks are looked for in the final states with either two leptons and two jets (ℓℓ+jj, ℓ=e, μ) or one lepton, missing transverse energy, and two jets (ℓν+jj, ℓ=e, μ). Apart from leptoquark investigations, the ℓℓ+jjfinal states are further studied in a search for W bosons with right-handed couplings that arise in left-right models. Third-generation scalar leptoquarks are looked for in the final state with two tau leptons and two b quarks or two top quarks (ττ+bband ττ+tt). The ττ+bbfinal state is also sensitive to stop pairs decaying through R-parity violating and conserving processes that are foreseen in some models of supersymmetry. In addition, results are shown for third-generation scalar leptoquarks in the final states bb+ννand tt+νν, reinterpreting searches for bottom and top squark pair production. 95% confidence level upper limits are set on the scalar leptoquark pair production cross section times branching fraction in each decay channel as a function of the leptoquark mass and the branching ratio of decay.
