Theoretical calculations for $t\bar{t}H$ production

Abstract

We calculate higher-order perturbative corrections for $t\bar{t}H$ 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 N${}^3$LO (aN${}^3$LO) in QCD and NLO in EW. Our aN${}^3$LO 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.
