Soft-gluon Corrections in FCNC Top-quark Production via Anomalous Gluon Couplings
نویسندگان
چکیده
We present a calculation of soft-gluon corrections in FCNC top-quark production via anomalous t-q-g couplings. The soft anomalous dimension matrix is explicitly calculated at one-loop accuracy. This calculation allows threshold resummation at next-to-leadinglogarithm accuracy. We also derive expressions for the soft-gluon corrections at NLO and at NNLO.

Anomalous tqV couplings and FCNC top quark production
We discuss FCNC top quark production via anomalous tqV couplings at the Tevatron and HERA colliders. We calculate higher-order soft-gluon corrections to such processes and demonstrate the stabilization of the cross section when these corrections are included. Presented at the DIS 2004 Workshop, Strbske Pleso, Slovakia, 14-18 April, 2004.
متن کاملFCNC top quark production via anomalous tqV couplings beyond leading order
We calculate flavor-changing neutral-current (FCNC) processes involving top-quark production via anomalous tqV couplings at the Tevatron and HERA colliders. We cover the FCNC processes pp̄ → tZ, pp̄ → tγ, pp̄ → tt, and ep → et. We go beyond leading order and include the effects of soft-gluon corrections through next-to-next-to-leading order. We demonstrate the stabilisation of the cross section wi...

متن کاملHigher-order soft gluon corrections in single top quark production at the LHC
I present a calculation of soft-gluon corrections to single top quark production in pp collisions at the LHC via the Standard Model partonic processes in the t and s channels and associated top quark and W boson production. Higher-order soft-gluon corrections through next-to-next-to-next-to-leading order (NNNLO) are calculated at next-to-leading logarithmic (NLL) accuracy. The soft-gluon correc...
