Azimuthal and Single Spin Asymmetries in Hard Scattering Processes

U. D'Alesio, F. Murgia

In this article we review the present understanding of azimuthal and single spin asymmetries for inclusive and semi-inclusive particle production in unpolarized and polarized hadro…

Single spin asymmetries in inclusive hadron production from SIDIS to hadronic collisions: universality and phenomenology

M. Boglione, U. D'Alesio, F. Murgia

In a perturbative QCD approach, with inclusion of spin and transverse momentum effects, experimental data on azimuthal asymmetries observed in polarized semi-inclusive deeply inela…

Nuclear physics inputs needed for geo-neutrino studies

G. Bellini, G. Fiorentini, A. Ianni +3

Geo-neutrino studies are based on theoretical estimates of geo-neutrino spectra. We propose a method for a direct measurement of the energy distribution of antineutrinos from decay…

Intrinsic parton motion soft mechanisms and the longitudinal spin asymmetry A_LL in high energy pp -> pi X

M. Anselmino, M. Boglione, U. D'Alesio +3

The longitudinal double spin asymmetry A_LL in the reaction pp --> pi X has been measured at RHIC with extremely interesting consequences. If the gluon polarization in a proton wer…

The Sivers single-spin asymmetry in photon-jet production

Alessandro Bacchetta, Cedran Bomhof, Umberto D'Alesio +2

We study a weighted asymmetry in the azimuthal distribution of photon-jet pairs produced in the process p^\uparrow p --> γjet X with a transversely polarized proton. We focus on th…

Transversity and Collins functions from SIDIS and e+e- data

M. Anselmino, M. Boglione, U. D'Alesio +4

A global analysis of the experimental data on azimuthal asymmetries in semi-inclusive deep inelastic scattering (SIDIS), from the HERMES and COMPASS Collaborations, and in e+e- -->…
