FCNC top quark production via anomalous tqV couplings beyond leading order
نویسندگان
چکیده
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 with respect to the variation of QCD scale, and we investigate the reach of the Tevatron and HERA colliders.

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 کاملSoft-gluon Corrections in FCNC Top-quark Production via Anomalous Gluon Couplings
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.

Using the constraint on the single top production cross-section obtained at the HERA collider, σ(ep → e tX), we evaluate an upper limit on coupling constant of the anomalous top quark interaction with a gluon via flavor-changing neutral current: |κtgq/Λ| . 0.4 TeV, BR(t → gq) < 13% E-mail: ashimova [email protected] E-mail: [email protected] Introduction In different extensions of the Standa...
متن کاملSingle Top Quark Production via FCNC Couplings at Hadron Colliders
We calculate single top–quark production at hadron colliders via the chromo–magnetic flavor–changing neutral current couplings t̄cg and t̄ug. We find that the strength for the anomalous t̄cg (t̄ug) coupling may be probed to κc/Λ = 0.092 TeV −1 (κu/Λ = 0.026 TeV ) at the Tevatron with 2 fb of data and κc/Λ = 0.013 TeV −1 (κu/Λ = 0.0061 TeV) at the LHC with 10 fb of data. The two couplings may be dis...
متن کاملStudy of the Top Quark FCNC
We study the one-loop contribution of the effective flavor changing neutral couplings (FCNC) tcZ to the charm quark electric dipole moment. Using the known limits on the top and charm quarks electric dipole moments, we place limits on these FCNC anomalous couplings. Corresponding author email address: [email protected] 1
