Resummation for $2\rightarrow n$ processes in single-particle-inclusive kinematics

We present a formalism and detailed analytical results for soft-gluon resummation for $2\rightarrow n$ processes in single-particle-inclusive (1PI) kinematics. This generalizes previous work on resummation for $2 \rightarrow 2$ processes in 1PI kinematics. We also present soft anomalous dimensions at one and two loops for certain $2 \rightarrow 3$ processes involving top quarks and Higgs or $Z$ bosons, and we provide some brief numerical results.

Soft-gluon corrections for single top quark production in association with electroweak bosons

We present results for higher-order soft-gluon radiative corrections for single top-quark production in association with electroweak bosons, including $tγ$ and $tZ$ production via anomalous FCNC couplings. We provide results for the total cross sections and differential distributions at LHC energies. We use $K$-factors to show the significance of the corrections compared to leading order, and we discuss uncertainties and the importance of the results.

Associated production of a top quark with a photon via anomalous couplings

We discuss the associated production of a top quark with a photon via anomalous $t$-$q$-$γ$ couplings, and present higher-order corrections from soft-gluon emission for the processes $gq \rightarrow tγ$ at LHC energies. We perform soft-gluon resummation at next-to-leading-logarithm accuracy and derive approximate next-to-next-to-leading order (aNNLO) double-differential cross sections. We calculate at aNNLO the total $tγ$ production cross sections and the top-quark transverse-momentum and rapidity distributions for various LHC energies, and show that the soft-gluon corrections are large and dominant in these processes.
