In particular, we study angularity distributions that are measured on jets with and without the SoftDrop grooming procedure. We begin our analysis exploiting state-of-the-art Monte Carlo parton shower simulations and we quantitatively assess the impact of next-to-leading order (NLO) matching and merging procedures. We then move to analytic resummation and arrive at an all-order expression that features the resummation of large logarithms at next-to-leading logarithmic accuracy (NLL) and is matched to the exact NLO result. Our predictions include the effect of soft emissions at large angles, treated as a power expansion in the jet radius, and non-global logarithms. Furthermore, matching to fixed-order is performed in such a way to ensure what is usually referred to as NLL′ accuracy. Our results account for realistic experimental cuts and can be easily compared to upcoming measurements of jet angularities from the LHC collaborations."],["dc.identifier.citation","Journal of High Energy Physics. 2021 Jul 13;2021(7):76"],["dc.identifier.doi","10.1007/JHEP07(2021)076"],["dc.identifier.pii","16174"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/88494"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/112901"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-448"],["dc.publisher","Springer Berlin Heidelberg"],["dc.relation.eissn","1029-8479"],["dc.rights.holder","The Author(s)"],["dc.subject","Jets"],["dc.subject","NLO Computations"],["dc.title","Jet angularities in Z+jet production at the LHC"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
