Single-spin asymmetries with two-hadron fragmentation functions
Alessandro Bacchetta, Marco Radici
Using the formalism of two-hadron fragmentation functions, we discuss single-spin asymmetries occurring in the production of two hadrons in the current region of deep inelastic sca…
Azimuthal single spin asymmetries in SIDIS in the light of chiral symmetry breaking
P. Schweitzer, A. Bacchetta
An attempt is made to understand the z-dependence of the azimuthal single spin asymmetries observed by the HERMES collaboration in terms of chiral models based on effective quark a…
Estimate of the Collins function in a chiral invariant approach
A. Bacchetta, R. Kundu, A. Metz +1
We estimate the Collins function at a low energy scale by calculating the fragmentation of a quark into a pion at the one-loop level in the chiral invariant model of Manohar and Ge…
Semi-inclusive vector meson production in DIS
A. Bacchetta, P. J. Mulders
We analyze one-particle inclusive DIS in the case when a spin-1 hadron (such as a vector meson) is observed in the final state. We consider only leading order contributions in 1/Q,…
The full spin structure of quarks in the nucleon
A. Bacchetta, M. Boglione, A. Henneman +1
We discuss bounds on the distribution and fragmentation functions that appear at leading order in deep inelastic 1-particle inclusive leptoproduction or in Drell-Yan processes. The…
