Spin and transverse momentum dependent Fracture Function in SIDIS
A. Kotzinian, M. Anselmino, V. Barone
The recently developed leading twist formalism for spin and transverse-momentum dependent fracture functions is shortly described. We demonstrate that the process of double hadron…
On the cos 2 phi asymmetry in unpolarized leptoproduction
Vincenzo Barone, Zhun Lu, Bo-Qiang Ma
We investigate the origin of the cos 2 phi azimuthal asymmetry in unpolarized semiinclusive DIS. The contributions to this asymmetry arising from the intrinsic transverse motion of…
Accessing transversity via J/Psi production in polarized p-pbar interactions
M. Anselmino, V. Barone, A. Drago +1
We discuss the possibility of a direct access to transversity distributions by measuring the double transverse spin asymmetry A_TT in p pbar --> J/Psi + X --> l^- l^+ + X processes…
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 chromodielec…
Transverse polarization distributions
V. Barone
I present a brief update on the transverse polarization distributions, focusing on model calculations and phenomenological perspectives.
The Charm-Strange Contribution to Charged-Current DIS Structure Functions
V. Barone, U. D'Alesio, M. Genovese
We review the present theoretical knowledge of the charm--strange contribution to charged--current DIS structure functions. In particular, the uncertainties arising from the choice…
A confinement model calculation of h_1(x)
V. Barone, T. Calarco, A. Drago
The transverse polarization distribution of quarks is computed in a confinement model, the chiral chromodielectric model. The flavor structure of , its evolutio…
Anomalous Evolution of Nonsinglet Nucleon Structure Functions
R. D. Ball, V. Barone, S. Forte +1
We calculate the scale dependence of nonsinglet nucleon structure functions. Due to anomalous axial symmetry breaking a large flavour asymmetry of the quark--antiquark sea is gener…
Unitarization of Structure Functions at Large
V. Barone, M. Genovese, N. N. Nikolaev +2
We discuss the effects of the -channel unitarization on the and dependence of structure functions. The unitarization is implemented at the level of photoabsorption c…
