A direct extraction of the Sivers distributions from spin asymmetries in pion and kaon leptoproduction
Anna Martin, Franco Bradamante, Vincenzo Barone
We present a point-by-point determination of the Sivers distributions from hadron leptoproduction data. The method, which relies on some simple assumptions, is based on the combine…
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…
Extracting the transversity distributions from single-hadron and dihadron production
Anna Martin, Franco Bradamante, Vincenzo Barone
We present a point-by-point determination of the valence transversity distributions from two different types of processes: single-hadron production and dihadron production, both in…
Heavy flavours in AA collisions: production, transport and final spectra
W. M. Alberico, A. Beraudo, A. De Pace +5
A multi-step setup for heavy-flavour studies in high-energy nucleus-nucleus (AA) collisions --- addressing within a comprehensive framework the initial Q-Qbar production, the propa…
A leading-twist beam-spin asymmetry in double-hadron inclusive lepto-production
Mauro Anselmino, Vincenzo Barone, Aram Kotzinian
We show that a new beam-spin asymmetry appears in deep inelastic inclusive lepto-production at low transverse momenta when a hadron in the target fragmentation region is observed i…
Double hadron lepto-production in the current and target fragmentation regions
Mauro Anselmino, Vincenzo Barone, Aram Kotzinian
We study the inclusive production of two hadrons in deep inelastic processes, l N ---> l h_1 h_2 X, with h_1 in the current fragmentation region (CFR) and h_2 in the target fragmen…
SIDIS in the target fragmentation region: polarized and transverse momentum dependent fracture functions
Mauro Anselmino, Vincenzo Barone, Aram Kotzinian
The target fragmentation region of semi-inclusive deep inelastic scattering is described at leading twist, taking beam and target polarizations into account. The formalism of polar…
Phenomenology of transverse-spin and transverse-momentum effects in hard processes
Vincenzo Barone
Some recent analyses of single-spin and azimuthal asymmetries in SIDIS and Drell-Yan processes, focusing in particular on Collins, Sivers and Boer-Mulders effects, are briefly revi…
General Helicity Formalism for Polarized Semi-Inclusive Deep Inelastic Scattering
M. Anselmino, M. Boglione, U. D'Alesio +4
We study polarized Semi-Inclusive Deep Inelastic Scattering (SIDIS) processes, within the QCD parton model and a factorization scheme, taking into account all transverse motions, o…
Transverse-Spin and Transverse-Momentum Effects in High-Energy Processes
Vincenzo Barone, Franco Bradamante, Anna Martin
The state of the art concerning transverse-spin and transverse-momentum phenomena in hard hadronic reactions is reviewed. An account is given of single-spin and azimuthal asymmetri…
Azimuthal asymmetries in unpolarized Drell-Yan processes and the Boer-Mulders distributions of antiquarks
Vincenzo Barone, Stefano Melis, Alexei Prokudin
Using a previous extraction of the quark Boer-Mulders distributions from semiinclusive deep inelastic scattering data, we fit the unpolarized Drell-Yan data on the asymm…
The Boer-Mulders effect in unpolarized SIDIS: an analysis of the COMPASS and HERMES data on the asymmetry
Vincenzo Barone, Stefano Melis, Alexei Prokudin
We present a phenomenological analysis of the asymmetry recently measured by the COMPASS and HERMES collaborations in unpolarized semi-inclusive deep inelastic scatterin…
Exclusive J/Psi electroproduction in a dual model
R. Fiore, L. L. Jenkovszky, V. K. Magas +2
Exclusive J/Psi electroproduction is studied in the framework of the analytic S-matrix theory. The differential and integrated elastic cross sections are calculated using the Modif…
A systematic phenomenological study of the asymmetry in unpolarized semi--inclusive DIS
Vincenzo Barone, Alexei Prokudin, Bo-Qiang Ma
We study the azimuthal asymmetry in unpolarized semi-inclusive DIS, taking into account both the perturbative contribution (gluon emission and splitting) and the non per…
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…
Double Transverse-Spin Asymmetries in Drell-Yan Processes with Antiprotons
Vincenzo Barone, Alessandro Cafarella, Claudio Coriano' +2
We present next-to-leading order predictions for double transverse-spin asymmetries in Drell--Yan dilepton production initiated by proton--antiproton scattering. The kinematic regi…
Probing nucleon strange asymmetry from charm production in neutrino deep inelastic scattering
Puze Gao, Bo-Qiang Ma
We propose a means to detect the nucleon strange quark-antiquark asymmetry, which is predicted as a non-perturbative effect, but still unchecked directly by available experiments.…
Azimuthal asymmetry in unpolarized Drell-Yan process
Zhun Lu, Bo-Qiang Ma
Taking into account the effect of final state interaction, we calculate the non-zero (naïve) -odd transverse momentum dependent distribution $h_1^{\perp}(x,\kp^2)$ of the pion i…
