3He structure and generalized parton distribution
Sergio Scopetta
Nuclear Generalized Parton Distributions (GPDs), a unique tool to access several crucial features of nuclear structure, could be measured in the coherent channel of hard exclusive…
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…
