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…
T-odd Transverse Momentum Distributions in Quark Models
A. Courtoy
We present a general formalism for the evaluation of time-reversal odd parton distributions. This formalism is applied to the evaluation of the two T-odd TMDs allowed at the twist-…
Analyzing the Boer-Mulders function within different quark models
A. Courtoy, S. Scopetta, V. Vento
A general formalism for the evaluation of time reversal odd parton distributions is applied here to calculate the Boer-Mulders function. The same formalism when applied to evaluate…
Studying the Sivers function by model calculations
A. Courtoy, S. Scopetta, V. Vento
A formalism is presented to evaluate the Sivers function in constituent quark models. A non-relativistic reduction of the scheme is performed and applied to the Isgur-Karl model. T…
Model calculations of the Sivers function satisfying the Burkardt Sum Rule
A. Courtoy, S. Scopetta, V. Vento
It is shown that, at variance with previous analyses, the MIT bag model can explain the available data of the Sivers function and satisfies the Burkardt Sum Rule to a few percent a…
Sivers Asymmetry for the proton and the neutron
S. Scopetta, A. Courtoy, F. Fratini +1
A formalism is presented to evaluate the Sivers function in constituent quark models. A non-relativistic reduction of the scheme is performed and applied to the Isgur-Karl model. T…
