Single-top transverse-momentum distributions at approximate NNLO

TL;DR

This paper provides approximate NNLO transverse-momentum distributions for single-top production at the LHC, derived from NNLL resummation of soft-gluon corrections, enhancing precision in theoretical predictions.

Contribution

It introduces a novel method to compute approximate NNLO $p_T$ distributions for single-top processes using NNLL resummation techniques.

Findings

Provides $p_T$ distributions for single-top and single-antitop at LHC energies.

Enhances theoretical precision with approximate NNLO calculations.

Applies to $t$-channel, $s$-channel, and $tW$ production modes.

Abstract

I present approximate next-to-next-to-leading-order (aNNLO) transverse-momentum ($p_T$) distributions in single-top production processes. The aNNLO results are derived from next-to-next-to-leading-logarithm (NNLL) resummation of soft-gluon corrections in the differential cross section. Single-top as well as single-antitop $p_T$ distributions are shown in $t$-channel, $s$-channel, and $tW$ production for LHC energies.
