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,…

Electromagnetic mass differences of SU(3) baryons within a chiral soliton model

Ghil-Seok Yang, Hyun-Chul Kim, Maxim V. Polyakov

We investigate the electromagnetic mass differences of SU(3) baryons, using an "model-independent approach" within a chiral soliton model. The electromagnetic self-energy correctio…

Towards a global analysis of generalized parton distributions

Kresimir Kumericki, Dieter Mueller

We discuss the complexity of GPD phenomenology, comment on the technological needs for a global analysis, and report on model and neural network fits to the photon electroproductio…

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…

Endpoint behavior of the pion distribution amplitude in QCD sum rules with nonlocal condensates

S. V. Mikhailov, A. V. Pimikov, N. G. Stefanis

Starting from the QCD sum rules with nonlocal condensates for the pion distribution amplitude, we derive another sum rule for its derivative and its "integral" derivatives---define…

Exclusive electroproduction revisited: treating kinematical effects

A. V. Belitsky, D. Mueller

Generalized parton distributions of the nucleon are accessed via exclusive leptoproduction of the real photon. While earlier analytical considerations of phenomenological observabl…

Leading Infrared Logarithms from Unitarity, Analyticity and Crossing

J. Koschinski, M. V. Polyakov, A. A. Vladimirov

We derive non-linear recursion equations for the leading infrared logarithms in massless non-renormalizable effective field theories. The derivation is based solely on the requirem…

Higher-order QCD perturbation theory in different schemes: From FOPT to CIPT to FAPT

A. P. Bakulev, S. V. Mikhailov, N. G. Stefanis

Results on the resummation of non-power-series expansions of the Adler function of a scalar, , and a vector, , correlator are presented within fractional analytic perturb…

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…

Intrinsic transverse parton momenta in deeply inelastic reactions

P. Schweitzer, T. Teckentrup, A. Metz

Intrinsic transverse parton momenta pT play an important role in the understanding of azimuthal/spin asymmetries in semi-inclusive deep-inelastic scattering (SIDIS) and the Drell-Y…

QCD isospin breaking ChPT low-energy constants from the instanton vacuum

K. Goeke, M. Musakhanov, M. Siddikov

In the framework of the instanton vacuum model we evaluate the Chiral Perturbation Theory (ChPT) low-energy constants h_3,l_7. We found that in the instanton vacuum model the const…

Momentum sum rules for fragmentation functions

S. Meissner, A. Metz, D. Pitonyak

Momentum sum rules for fragmentation functions are considered. In particular, we give a general proof of the Schäfer-Teryaev sum rule for the transverse momentum dependent Collins…
