Asymmetries involving dihadron fragmentation functions: from DIS to e+e- annihilation
Alessandro Bacchetta, Federico A. Ceccopieri, Asmita Mukherjee +1
Using a model calculation of dihadron fragmentation functions, we fit the spin asymmetry recently extracted by HERMES for the semi-inclusive pion pair production in deep-inelastic…
Transverse-momentum distributions in a diquark spectator model
A. Bacchetta, F. Conti, M. Radici
All the leading-twist parton distribution functions are calculated in a spectator model of the nucleon, using scalar and axial-vector diquarks. Single gluon rescattering is used to…
Parton fragmentation in the vacuum and in the medium
S. Albino, F. Anulli, F. Arleo +38
We present the mini-proceedings of the workshop on ``Parton fragmentation in the vacuum and in the medium'' held at the European Centre for Theoretical Studies in Nuclear Physics a…
Nucleon Spin Structure with hadronic collisions at COMPASS
Marco Radici, Francesco Conti, Alessandro Bacchetta +1
In order to illustrate the capabilities of COMPASS using a hadronic beam, I review some of the azimuthal asymmetries in hadronic collisions, that allow for the extraction of transv…
Evolution equations for extended dihadron fragmentation functions
Federico A. Ceccopieri, Marco Radici, Alessandro Bacchetta
We consider dihadron fragmentation functions, describing the fragmentation of a parton in two unpolarized hadrons, and in particular extended dihadron fragmentation functions, expl…
Transversity and inclusive two-pion production
Marco Radici
A model for dihadron fragmentation functions is briefly outlined, that describes the fragmentation of a quark in two unpolarized hadrons. The parameters are tuned to the output of…
