Taming singularities in transverse-momentum-dependent parton densities
I. O. Cherednikov, N. G. Stefanis
We propose a consistent treatment of divergences emerging in the computation of transverse-momentum-dependent parton densities in leading -order of QCD perturbation theory.
UHE neutrinos: higher twists, scales, saturation
R. Fiore, V. R. Zoller
It is shown that in the ultra-high energy neutrino interactions the higher twist corrections brought about by the non-conservation of the top-bottom current dramatically change the…
Central Diffractive Processes at the Tevatron, RHIC and LHC
L. A. Harland-Lang, V. A. Khoze, M. G. Ryskin +1
Central exclusive production (CEP) processes in high-energy hadron collisions offer a very promising framework for studying both novel aspects of QCD and new physics signals. We re…
Nonlinear Regge Trajectories in Theory and Practice
V. A. Petrov
The problems related to nonlinear behavior of Regge trajectories (RT) and their renormalization group invariance are discussed.
Diffractive jets production in pp-collisions
D. Yu. Ivanov, V. M. Braun, A. Schäfer
We consider the exclusive diffractive dissociation of a proton into three jets with large transverse momenta in the double-logarithmic approximation of perturbative QCD. This proce…
