نویسندگان
چکیده
We compute the non-factorisable contribution to two-loop helicity amplitude for $t$-channel single-top production, last missing piece of virtual corrections this process. Our calculation employs analytic reduction master integrals and auxiliary mass flow method their fast numerical evaluation. study impact these on basic observables that are measured experimentally in production

NLO single-top production matched with shower in POWHEG: s- and t-channel contributions
We present a next-to-leading order calculation of single-top production interfaced to Shower Monte Carlo programs, implemented according to the POWHEG method. A detailed comparison with MC@NLO and PYTHIA is carried out for several observables, for the Tevatron and LHC colliders.
متن کاملComprehensive 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...
متن کاملTop-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.
متن کاملNext-to-leading-order predictions for t-channel single-top production at hadron colliders.
We present the predictions at next-to-leading order (NLO) in the strong coupling for the single-top cross section in the t channel at the Tevatron and the LHC. Our calculation starts from the 2-->3 Born amplitude gq-->tb[over ]q;{'}, keeping the b-quark mass nonzero. A comparison is performed with a traditional NLO calculation of this channel based on the 2-->2 Born process with a bottom quark ...
متن کاملElectroweak Corrections to t-channel single top production at the LHC
— We describe the computation of the O(α) corrections for single top (and single anti-top) production in the t-channel at hadron colliders. We show also The genuine one loop SUSY contribution to these processes. Such contributions are generally quite modest in the mSUGRA scenario. The experimental observables would therefore only practically depend, in this framework, on the CKM Wtb coupling.
