NLL BFKL and NNLO
In the limit of center-of-mass energy much greater than the momentum transfer, ŝ ≫ |t̂|, any scattering process is dominated by gluon exchange in the cross channel. Building upon this fact, the BFKL theory [ 1] models stronginteraction processes with two large and disparate scales, by resumming the radiative corrections to parton-parton scattering. This is achieved to leading logarithmic (LL) ac...
متن کاملBFKL at NNLO
We present a recent determination of an approximate expression for the O(α3s) contribution χ2 to the kernel of the BFKL equation. This includes all collinear and anticollinear singular contributions and is derived using duality relations between the GLAP and BFKL kernels. † Talk presented at 12 International Conference on Elastic and Diffractive Scattering: Forward Physics and QCD, DESY, Hambur...
متن کاملVector Meson production from NLL BFKL
The amplitude for the forward electroproduction of two light vector mesons can be written completely within perturbative QCD in the Regge limit with next-to-leading accuracy, thus providing the first example of a physical application of the BFKL approach at the next-to-leading order. We study in the case of equal photon virtualities the main systematic effects, by considering a different repres...
متن کاملThe Status of Nll Bfkl A
This talk summarises the current status of the NLL corrections to BFKL physics and discusses the question of small-x factorisation.
متن کاملA Global Fit to Scattering Data with NLL BFKL Resummations
We perform a global parton fit to DIS and related data, including next-to-leading logarithmic (NLL) BFKL resummations in both the massless and massive sectors. The resummed fit improves over a standard next-to-leading order (NLO) DGLAP fit, with a positive definite gluon at the input scale as opposed to the negative gluon seen at NLO. Furthermore, the predicted longitudinal structure function i...
