Gluon Spin in a Quark Model
V. Barone, T. Calarco, A. Drago
We compute the gluon polarization and the gluon total angular momentum in the Isgur-Karl quark model. Taking into account self-interaction contributions, we obtain for…
Flavor Asymmetry of the Polarized Light Sea: Models vs. Data
V. Barone, T. Calarco, A. Drago +1
The flavor asymmetry of the polarized light sea, , discriminates between different model calculations of helicity densities. We show that the chiral chromodiel…
An improved study of HCO+ and He system: interaction potential, collisional relaxation and pressure broadening
F. Tonolo, L. Bizzocchi, M. Melosso +4
In light of its ubiquitous presence in the interstellar gas, the chemistry and reactivity of the HCO+ ion requires special attention. The availability of up-to-date collisional dat…
Measurement of -weighted Sivers asymmetries in leptoproduction of hadrons
M. G. Alexeev, G. D. Alexeev, A. Amoroso +209
The transverse spin asymmetries measured in semi-inclusive leptoproduction of hadrons, when weighted with the hadron transverse momentum , allow for the extraction of importan…
A phenomenological analysis of azimuthal asymmetries in unpolarized semi-inclusive deep inelastic scattering
V. Barone, M. Boglione, J. O. Gonzalez Hernandez +1
We present a phenomenological analysis of the cos-phi and cos-2phi asymmetries in unpolarized semi-inclusive deep inelastic scattering, based on the recent multidimensional data re…
SIDIS in target fragmentation region
A. Kotzinian, M. Anselmino, V. Barone
We shortly describe the leading twist formalism of spin and transverse-momentum dependent fracture functions recently developed and present results for the production of spinless h…
