Evaluating master integrals in non-factorizable corrections to t-channel single-top production at NNLO QCD
نویسندگان
چکیده
A bstract We studied the two-loop non-factorizable Feynman diagrams for t -channel single-top production process in quantum chromodynamics. present a systematic computation of master integrals with one internal massive propagator which complete uniform transcendental basis can be built. The are derived by means canonical differential equations and integrals. results expressed form Goncharov polylogarithm functions, whose variables scalar products external momenta, as well masses top quark W boson. also gave discussion on potential elliptic sectors.

On the NNLO QCD corrections to single-top production at the LHC
We present a fully-differential calculation of the NNLO QCD corrections to the t-channel mechanism for producing single top quarks at the LHC. We work in the structure function approximation, computing QCD corrections to the lightand heavy-quark lines separately and neglecting the dynamical cross-talk between the two. The neglected contribution, which appears at NNLO for the first time, is colo...
متن کاملQCD corrections to FCNC single top production at HERA
We calculate first-order QCD corrections to the cross section for single top quark production mediated by flavor changing neutral currents (FCNC) in ep collisions at the HERA collider. We find that the uncertainty due to the choice of the QCD scale is significantly reduced. This study is motivated by the current experimental work for limits on the FCNC single top cross section. On leave of abse...
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.

with σ the physical cross section, σ̂ the perturbatively calculable hard scattering factor, and φf/hi the parton distribution for parton f in hadron hi. The partonic hard-scattering factors σ̂ include soft and virtual corrections, arising from soft-gluon emission and loop diagrams, which manifest themselves as plus distributions and delta functions with respect to a kinematical variable xth that ...
متن کاملOne-loop QCD corrections to quark scattering at NNLO∗
We present the O(α s) virtual QCD corrections to unlike-quark qq̄ → q q̄ and like-quark scattering qq̄ → qq̄ due to the interference of one-loop amplitudes with one-loop amplitudes. The structure of the infrared divergences agrees with that predicted by Catani. The results are expressed in an analytic form so that the relevant expressions for crossed scattering processes can be obtained in a straig...
