Top-quark transverse-momentum distributions int-channel single-top production

Top-quark Transverse-momentum Distributions in T-channel Single-top Production

I present approximate next-to-next-to-leading-order (NNLO) top-quark transverse momentum, pT , distributions in t-channel single-top production. These distributions are derived from next-to-next-to-leading-logarithm (NNLL) soft-gluon resummation. Theoretical results for the single top as well as the single antitop pT distributions are shown for LHC and Tevatron energies.

Single-top Transverse-momentum Distributions at Approximate NNLO

I present approximate next-to-next-to-leading-order (aNNLO) transverse-momentum (pT ) 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 pT distributions are shown in t-channel, s-channel, and tW production for L...

Transverse-momentum resummation for top-quark pairs at hadron colliders.

We develop a framework for a systematic resummation of the transverse momentum distribution of top-quark pairs produced at hadron colliders based on effective field theory. Compared to Drell-Yan and Higgs production, a novel soft function matrix is required to account for the soft gluon emissions from the final states. We calculate this soft function at the next-to-leading order, and perform th...

Comprehensive measurements of t-channel single top-quark production

This article presents measurements of the t-channel single top-quark (t) and top-antiquark (t̄) total production cross sections σðtqÞ and σðt̄qÞ, their ratio Rt 1⁄4 σðtqÞ=σðt̄qÞ, and a measurement of the inclusive production cross section σðtqþ t̄qÞ in proton-proton collisions at ffiffi s p 1⁄4 7 TeV at the LHC. Differential cross sections for the tq and t̄q processes are measured as a function of t...
