3He structure from coherent hard exclusive processes
S. Scopetta
Hard exclusive processes, such as deep electroproduction of photons and mesons off nuclear targets, could give access, in the coherent channel, to nuclear generalized parton distri…
The effects of nuclear structure on generalized parton distributions of 3He
S. Scopetta
The effect of the nuclear medium on generalized parton distributions (GPDs) is studied for the 3He nucleus, through a realistic microscopic analysis. In Impulse Approximation, Ferm…
Nuclear effects on generalized parton distributions of 3He
Sergio Scopetta
The relevance of measuring Generalized Parton Distributions (GPDs) of nuclei is stressed and the unique possibilities offered by nuclear few body systems is emphasized. A realistic…
Relativity and constituent quark structure in model calculations of parton distributions
Santiago Noguera, Sergio Scopetta, Vicente Vento
According to recent studies, Parton Distribution Functions (PDFs) and Generalized Parton Distributions (GPDs) can be evaluated in a Constituent Quark Model (CQM) scenario, consider…
Helicity-dependent generalized parton distributions and composite constituent quarks
Sergio Scopetta, Vicente Vento
An approach, recently proposed to calculate the nucleon generalized parton distributions (GPDs) in a constituent quark model (CQM) scenario, in which the constituent quarks are tak…
Generalized Parton Distributions of ^3He
Sergio Scopetta
A realistic microscopic calculation of the unpolarized quark Generalized Parton Distribution (GPD) of the nucleus is presented. In Impulse Approximation, is…
