Helicity dependent parton distributions
Sergio Scopetta, Vicente Vento
The helicity dependent parton distributions describe the number density of partons with given longitudinal momentum x and given polarization in a hadron polarized longitudinally wi…
The eta-photon transition form factor
S. Noguera, S. Scopetta
The eta-photon transition form factor is evaluated in a formalism based on a phenomenological description at low values of the photon virtuality, and a QCD-based description at hig…
Transversity studies with protons and light nuclei
Sergio Scopetta
A general formalism to evaluate time-reversal odd transverse momentum dependent parton distributions (T-odd TMDS) is reviewed and applied to the calculation of the leading-twist qu…
Non-perturbative momentum dependence of the coupling constant and hadronic models
A. Courtoy, S. Scopetta, V. Vento
Models of hadron structure are associated with a hadronic scale which allows by perturbative evolution to calculate observables in the deep inelastic region. The resolution of Dyso…
