The search uses 36.1 fb- 1 of data collected in 2015 and 2016 by the ATLAS experiment at the Large Hadron Collider. Decays of the excited electron into an electron and a pair of quarks (eqq¯) are targeted in final states with two electrons and two hadronic jets, and decays via a gauge interaction into a neutrino and a W boson (νW) are probed in final states with an electron, missing transverse momentum, and a large-radius jet consistent with a hadronically decaying W boson. No significant excess is observed over the expected backgrounds. Upper limits are calculated for the pp→ ee∗→ eeqq¯ and pp→ ee∗→ eνW production cross sections as a function of the excited electron mass me∗ at 95% confidence level. The limits are translated into lower bounds on the compositeness scale parameter Λ of the model as a function of me∗. For me∗<0.5 Te, the lower bound for Λ is 11 Te. In the special case of me∗=Λ, the values of me∗<4.8 Te are excluded. The presented limits on Λ are more stringent than those obtained in previous searches. © 2019, CERN for the benefit of the ATLAS collaboration. en_US dc.language.iso eng en_US dc.publisher Springer New York LLC en_US dc.rights info:eu-repo/semantics/openAccess dc.subject Collisions en_US dc.subject jets en_US dc.subject proton–proton collisions en_US dc.title Search for excited electrons singly produced in proton–proton collisions at √s=13Te with the ATLAS experiment at the LHC en_US dc.type article en_US dc.relation.journal European Physical Journal C en_US dc.contributor.department TOBB ETU, Faculty of Engineering, Department of Material Science & Nanotechnology Engineering en_US dc.contributor.department TOBB ETÜ, Mühendislik Fakültesi, Malzeme Bilimi ve Nanoteknoloji Mühendisliği Bölümü tr_TR dc.identifier.volume 9 dc.identifier.issue 9 dc.contributor.orcid https://orcid.org/0000-0003-2340-748X dc.identifier.wos WOS:000490526000004 dc.identifier.scopus 2-s2.0-85073185035 dc.contributor.tobbetuauthor Sultansoy, Saleh F. dc.identifier.doi 10.1140/epjc/s10052-019-7295-1 dc.relation.publicationcategory Makale - Uluslararası Hakemli Dergi - Kurum Öğretim Elemanı tr_TR
