Abstract We calculate the complete soft-gluon corrections for the production of colorless final states through N3LO in single-particle-inclusive kinematics. We present explicit analytical results and use them to study higher-order QCD corrections for

Abstract We study higher-order QCD corrections for the production of a top–antitop quark pair ( $$t{{\bar{t}}}$$ t t ¯ production) at the Large Hadron Collider in the Standard Model Effective Field Theory. We consider effects of new physics parame

We study higher-order QCD corrections for the associated production of a top-antitop quark pair and a W boson (tt¯W production) in proton-proton collisions. We calculate approximate NNLO (aNNLO) and approximate N3LO (aN3LO) cross sections, with seco

Abstract We study QCD corrections for the associated production of a single top quark and a photon ( $$tq\gamma $$ t q γ production) at hadron colliders. We calculate the NLO cross section at LHC and future collider energies for a variety of kinemat

We study soft-gluon corrections for the associated production of a single top quark and a Z boson (tqZ production) at hadron colliders. We find that the radiative corrections are dominated by soft-gluon emission. We derive an approximate NNLO (aNNLO)

Abstract We discuss cross sections for tW production in proton-proton collisions at the LHC and at higher-energy colliders with energies of up to 100 TeV. We find that, remarkably, the soft-gluon corrections are numerically dominant even at very high

Abstract We study the production of a single top quark in association with a heavy extra $$Z'$$ Z′ at hadron colliders in new physics models with and without flavor-changing neutral-current (FCNC) couplings. We use QCD soft-gluon resummation and th

We present theoretical results with soft-gluon corrections for two separate processes: (1) the production of a single top quark in association with a $W$ boson in the Standard Model; and (2) the production of a single top quark in association with

I present results for soft anomalous dimensions through three loops for several processes involving the production of top quarks. In particular, I discuss single-top and top-pair production. I also present some numerical results for double-differe

I present results for soft anomalous dimensions through three loops for many QCD processes. In particular, I give detailed expressions for soft anomalous dimensions in various processes with electroweak and Higgs bosons as well as single top quarks a
