Generalized Parton Distributions and the structure of the constituent quark
Sergio Scopetta, Vicente Vento
In a scenario where the constituent quarks are composite systems, Generalized Parton Distributions (GPDs) are built from wave functions to be evaluated in a Constituent Quark Model…
Generalized parton distributions in constituent quark models
Sergio Scopetta, Vicente Vento
An approach is proposed to calculate Generalized Parton Distributions (GPDs) in a Constituent Quark Model (CQM) scenario. These off-diagonal distributions are obtained from momentu…
Orbital Angular Momentum Parton Distributions in Quark Models
S. Scopetta, V. Vento
At the low energy, {\sl hadronic}, scale we calculate Orbital Angular Momentum (OAM) twist-two parton distributions for the relativistic MIT bag model and for non-relativistic quar…
Semi-inclusive deep inelastic lepton scattering off complex nuclei
C. Ciofi degli Atti, L. P. Kaptari, S. Scopetta
It is shown that in semi-inclusive deep inelastic scattering (DIS) of electrons off a complex nucleus A, the detection, in coincidence with the scattered electron, of a nucleus (A-…
A quark model analysis of the transversity distribution: Next to leading order evolution
Sergio Scopetta, Vicente Vento
The feasibility of measuring chiral-odd parton distribution functions in polarized Drell-Yan and semi-inclusive experiments has renewed theoretical interest in their study. Not lon…
