The intricate color structure of soft gluon emission at large angles renders resummed calculations highly non-trivial in this case. We automate all ingredients necessary for the color evolution of the soft function at next-to-leading- logarithmic accuracy, namely the selection of the color bases and the projections of color operators and Born amplitudes onto those bases. Explicit results for all QCD processes with up to 2 -> 5 partons are given. We also devise a new tree-level matching scheme for resummed calculations which exploits a quasi-local subtraction based on the Catani-Seymour dipole formalism. We implement both resummation and matching in the Sherpa event generator. As a proof of concept, we compute the resummed and matched transverse-thrust distribution for hadronic collisions."],["dc.identifier.doi","10.1007/JHEP02(2015)106"],["dc.identifier.isi","000349914200001"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11623"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37899"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation","info:eu-repo/grantAgreement/EC/FP7/315877/EU//MCNETITN"],["dc.relation.issn","1029-8479"],["dc.relation.orgunit","Fakultät für Physik"],["dc.rights","CC BY 4.0"],["dc.title","Soft evolution of multi-jet final states"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
