Two-hadron semi-inclusive production including subleading twist
Alessandro Bacchetta, Marco Radici
We extend the analysis of two-hadron fragmentation functions to the subleading twist, discussing also the issue of color gauge invariance. Our results can be used anywhere two unpo…

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…
