We present an extension of the string+3P0 model of hadronization that includes the production and decays of polarized spin-1/2 baryons. The new model predicts: a Collins effect for baryon emission in transversely polarized quark fragmentations, the transverse spin transfer from the quark to the baryon, a baryon transverse polarization with respect to the production plane in unpolarized quark...

Di-hadron fragmentation functions represent an alternative method for extracting the transversity PDF, complementary to the Collins effect.

However, data on unpolarized inclusive cross sections for charged di-hadron production have only become available recently.
In this talk, I will present a new extraction of the unpolarized di-hadron fragmentation functions up to NNLO accuracy, carried... -

Future planned lepton colliders, both in the circular and linear configurations, can effectively work as virtual and quasi-real photon-photon colliders and are expected to stimulate an intense physics program in the next few years. In this paper, we suggest to consider photon-photon scattering as a useful source of information on transverse momentum dependent fragmentation functions (TMD FFs),...
