Daniel Lechner (Vienna): Electroweak and Finite-Lifetime Corrections for Boosted Top Quark Production

Jet mass measurements for processes involving boosted top quark pair-productionat the HL-LHC or future lepton colliders are a very promising tool for high-precisionmeasurements of the top quark mass in a well-defined renormalization scheme.
Apart from including QCD corrections and resummations, for which well-developed frameworks exist, eventually also electroweak and finite-lifetime effects need to beaccounted for systematically.
For boosted top quark initiated inclusive jets we apply an electroweak Soft-Collinear-Effective-Theory (SCET) framework that allows for a coherent resummation ofelectroweak Sudakov and rapidity logarithms and finite-lifetime effects together withlarge logs from QCD.
Apart from double-top-resonant effects, the factorization approach can also account for single-resonant effects, which are related to the interference of final states originatingfrom top quark decays and background processes leading to the top decay final state.
Concretely we address electroweak effects in inclusive (hemisphere mass) top-dijet production at lepton colliders.
