Non-commuting ETC corrections to zt¯t vertex
In this paper we calculate the corrections to ztt̄ couplings induced by non-commuting ETC interactions. The extra parameters δg L, s 2 and 1 x of non-commuting ETC models and the usual SM parameters will be be assumed to be determined from a global fit to the LEP 1 EW data. We find that in the heavy (light) case F t L is modified by at most 4% (2.8%) relative to its SM value provided δRb < .0088...
متن کاملVirtual Next - to - Leading Corrections to the Lipatov Vertex
We compute the virtual next-to-leading corrections to the Lipatov vertex in the helicity-amplitude formalism. These agree with previous results by Fadin and collaborators, in the conventional dimensional-regularization scheme. We discuss the choice of reggeization scale in order to minimize its impact on the next-toleading-logarithmic corrections to the BFKL equation. On leave of absence from I...

متن کاملRadiative corrections to quark-quark-Reggeon vertex in QCD.
One loop corrections to the coupling of the reggeized gluon to quarks are calculated in QCD. Combining this result with the known corrections to the gluon-gluon-reggeon vertex, we check the self-consistency of the representation of the amplitudes with gluon quantum numbers and negative signature in the t-channel in terms of Regge pole contribution. 1. Introduction Since a long time it has been ...
متن کاملAN ANALYSIS OF NON–OBLIQUE CORRECTIONS TO THE Zbb̄ VERTEX
We present a model–independent analysis of the Zbb̄ vertex, with the aim of constraining contributions of new physics to the leftand right–handed couplings of the b. We find that the left–handed coupling of the b is quite narrowly constrained by present data, but that the right–handed coupling is still largely unconstrained.
