To this end we present exact NLO EW results for pp → e+e−μ+μ−, and, for the first time, for pp → e+e−μ+μ−j, and compare them to the EW virtual and NLL Sudakov approximation. We then match the exact NLO EW result to the resummed Sudakov logarithms to achieve an improved NLO EW + NLL EW sud exp $ \\mathrm{NLO}\\ \\mathrm{EW}+\\mathrm{NLL}\\ {\\mathrm{EW}}_{\\mathrm{sud}}^{\\mathrm{exp}} $ result. Further, we discuss the inclusion of the above EW corrections in MePs@Nlo event simulations in the framework of the Sherpa event generator. We present detailed phenomenological predictions for inclusive ZZ and ZZj production taking into account the dominant EW corrections through the EW virtual approximation, as well as through (exponentiated) EW Sudakov logarithms."],["dc.identifier.citation","Journal of High Energy Physics. 2022 Jun 13;2022(6):64"],["dc.identifier.doi","10.1007/JHEP06(2022)064"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/111436"],["dc.language.iso","en"],["dc.rights","CC BY 4.0"],["dc.rights.holder","The Author(s)"],["dc.subject","NLO Computations"],["dc.subject","QCD Phenomenology"],["dc.title","Higher-order EW corrections in ZZ and ZZj production at the LHC"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]
