Search for excited electrons and muons with 5/fb of proton–proton collisions at √s = 7 TeV with the ATLAS detector

The ATLAS detector is used to search for excited leptons in the electromagnetic radiative decay channel l∗ → lγ. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of ∼ 5/fb. No evidence for excited leptons is fo...

description The ATLAS detector is used to search for excited leptons in the electromagnetic radiative decay channel l∗ → lγ. Results are presented based on the analysis of pp collisions at a center-of-mass energy of 7 TeV corresponding to an integrated luminosity of ∼ 5/fb. No evidence for excited leptons is found, and limits are set on the compositeness scale Λ as a function of the excited lepton mass m_l∗. In the special case where Λ = m_l∗ , excited electron and muon masses below 2.0 TeV and 1.9 TeV are excluded at 95% C.L., respectively.
