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.
Role and Properties of Wilson Lines in Transverse-Momentum-Dependent Parton Distribution Functions
N. G. Stefanis, I. O. Cherednikov, A. I. Karanikas
We summarize the renormalization-group properties of transverse-momentum dependent (TMD) parton distribution functions (PDF)s arguing that in the light-cone gauge the overlapping u…
On correlations in high-energy hadronic processes and the CMS ridge: A manifestation of quantum entanglement?
I. O. Cherednikov, N. G. Stefanis
We discuss the possibility of quantum entanglement for pairs of charged particles produced in high-energy -collisions at the LHC. Using a framework of interacting Wilson lines,…
Transverse-momentum parton densities: gauge links, divergences and soft factor
I. O. Cherednikov, N. G. Stefanis
We discuss the state-of-the-art of the theory of transverse-momentum dependent parton densities (TMD)s, paying special attention to their renormalization properties, the structure…
Wilson lines in transverse-momentum dependent parton distribution functions with spin degrees of freedom
I. O. Cherednikov, A. I. Karanikas, N. G. Stefanis
We propose a new framework for transverse-momentum dependent parton distribution functions, based on a generalized conception of gauge invariance which includes into the Wilson lin…
