Off-shell $t\bar{t}j$ production and top quark mass studies at the LHC
Abstract
Precision studies of the properties of the top quark represent a cornerstone of the LHC physics program. In this contribution we focus on the production of pairs in association with one hard jet and in particular on its connection with precision measurements of the top quark mass at the LHC. We report a summary of a full calculation of the process at NLO QCD accuracy, which describes production with leptonic decays beyond the Narrow Width Approximation (NWA), and discuss the impact of the off-shell effects through comparisons with NWA. Finally we explore the sensitivity of in the context of top-quark mass extraction with the template method, considering two benchmark observables as case studies.
