Direct Bayesian Inference of Helicity Amplitudes from Detector-Level Scattering Data
Bhawani Singh, Harut Avakian, Shohini Bhattacharya +8
Helicity amplitudes give the most complete description of a variety of scattering reactions used in studies of strong interactions, but they cannot be measured directly: experiment…
Extraction of the higher-twist parton distribution from CLAS data
Aurore Courtoy, Angel Miramontes, Harut Avakian +2
This manuscript presents the new analysis of recent CLAS and CLAS12 data aimed at the extraction of . This publication benefits from a proof-of-principle analysis of a smalle…
Studies of Transverse Momentum Dependent Parton Distributions and Bessel Weighting
M. Aghasyan, H. Avakian, E. De Sanctis +5
In this paper we present a new technique for analysis of transverse momentum dependent parton distribution functions, based on the Bessel weighting formalism. The procedure is appl…
Constraints on spin-dependent parton distributions at large x from global QCD analysis
P. Jimenez-Delgado, H. Avakian, W. Melnitchouk
We investigate the behavior of spin-dependent parton distribution functions (PDFs) at large parton momentum fractions x in the context of global QCD analysis. We explore the constr…

TMDs in the bag model
H. Avakian, A. V. Efremov, P. Schweitzer
Leading and subleading twist transverse momentum dependent parton distribution functions (TMDs) are studied in a quark model framework provided by the bag model. A complete set of…
Quark orbital angular momentum: can we learn about it from GPDs and TMDs?
H. Avakian, A. V. Efremov, P. Schweitzer +2
It is known how to access information on quark orbital angular momentum from generalized parton distribution functions, in a certain specified framework. It is intuitively expected…

Insights on non-perturbative aspects of TMDs from models
H. Avakian, A. V. Efremov, P. Schweitzer +3
Transverse momentum dependent parton distribution functions are a key ingredient in the description of spin and azimuthal asymmetries in deep-inelastic scattering processes. Recent…
Pretzelosity distribution function
H. Avakian, A. V. Efremov, P. Schweitzer +1
The 'pretzelosity' distribution is discussed. Theoretical properties, model results, and perspectives to access experimental information on this leading twist, transverse momentum…
