Partial-wave analysis of two-hadron fragmentation functions
Alessandro Bacchetta, Marco Radici
We reconsider the option of extracting the transversity distribution by using interference fragmentation functions into two leading hadrons inside the same current jet. To this end…
Probing the transverse spin of quarks in deep inelastic scattering
A. Bacchetta
To identify some way to measure the quark transversity, this thesis analyzes one-particle and two-particle inclusive deep inelastic scattering, where one and two of the outgoing ha…
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…
Estimate of the Collins fragmentation function in a chiral invariant approach
A. Bacchetta, R. Kundu, A. Metz +1
We predict the features of the Collins function, which describes the fragmentation of a transversely polarized quark into an unpolarized hadron, by modeling the fragmentation proce…
