Structure of the nucleon at leading and subleading twist in the covariant parton model
S. Bastami, A. V. Efremov, P. Schweitzer +2
The covariant parton model is generalized to describe quark correlators in a systematic way. Previous results are reproduced for the T-even leading-twist transverse momentum depend…
Applications of the WW-type approximation to SIDIS
S. Bastami, H. Avakian, A. V. Efremov +8
We explore the complete cross-section for the production of unpolarized hadrons in semi-inclusive deep-inelastic scattering up to power-suppressed terms in the…
Causality constraints on TMD PDF
A. V. Efremov, A. A. Vladimirov
In this short note, we discuss constraints on the transverse momentum dependent factorization formulae coming from the causality properties for the hadronic tensor.
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…
The transverse momentum dependent distribution functions in the bag model
H. Avakian, A. V. Efremov, P. Schweitzer +1
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…
Recent developments in nucleon spin structure with focus on h_{1L}^{\perp} and pretzelosity h_{1T}^\perp
H. Avakian, A. V. Efremov, P. Schweitzer +2
The leading twist transverse momentum dependent parton distribution functions h_{1L}^{\perp} and h_{1T}^\perp, which is sometimes called "pretzelosity," are studied. For h_{1L}^{\p…
