Theoretical calculations for t tH production
Nikolaos Kidonakis, Nodoka Yamanaka
Abstract
We calculate higher-order perturbative corrections for t tH production. By adding second-order and third-order soft-gluon corrections to NLO QCD and NLO electroweak (EW) results, we present total and differential cross sections at LHC energies through approximate N3LO (aN3LO) in QCD and NLO in EW. Our aN3LO QCD + NLO EW results provide significant enhancements and a reduced scale dependence for the cross section and the top-quark transverse-momentum and rapidity distributions.
