Search for excited leptons in proton-proton collisions at root s=7 TeV with the ATLAS detector
2012 (English)In: Physical Review D, ISSN 1550-7998, Vol. 85, no 7, 072003- p.Article in journal (Refereed) Published
The ATLAS detector is used to search for excited leptons in the electromagnetic radiative decay channel l* -> l gamma. 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 2.05 fb(-1). No evidence for excited leptons is found, and limits are set on the compositeness scale Lambda as a function of the excited lepton mass m(l*). In the special case where Lambda = m(l*), excited electron and muon masses below 1.87 TeV and 1.75 TeV are excluded at 95% C.L., respectively.
