Spin microscopy with enhanced Wilson lines in the TMD parton densities
I. O. Cherednikov, A. I. Karanikas, N. G. Stefanis
We discuss the possibility of non-minimal gauge invariance of transverse-momentum-dependent parton densities (TMDs) that allows direct access to the spin degrees of freedom of ferm…
Geometry of gauge links in operator definitions of transverse-momentum dependent PDFs: A comparative view
Igor O. Cherednikov
Different approaches to the problem of a gauge-invariant operator definition of transverse-momentum dependent parton densities (TMDs) are reviewed and compared from the point of vi…
Wilson lines in the operator definition of TMDs: spin degrees of freedom and renormalization
I. O. Cherednikov, A. I. Karanikas, N. G. Stefanis
A generalized idea of gauge invariance, that embodies into the Wilson lines the spin-dependent Pauli term , is applied to set up a new framework for the oper…
Transverse-momentum-dependent parton distributions at the edge of the lightcone
I. O. Cherednikov, N. G. Stefanis
We present a completely gauge-invariant operator definition of transverse-momentum-dependent parton densities (TMD), supplied with longitudinal lightlike gauge links as well as tra…
Evolution of transverse-momentum-dependent densities
I. O. Cherednikov, N. G. Stefanis
We discuss different operator definitions of the transverse-momentum dependent (TMD) parton densities from the point of view of their renormalization-group (RG) properties and UV e…
Theory of transverse-momentum parton densities: solving the puzzle of divergences
I. O. Cherednikov
The current status of the theoretical understanding of the transverse-momentum dependent parton densities (TMDs) is discussed. Special attention is payed to the difference between…
