Description
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 out in collaboration with Paris-Saclay, using both a model-inspired and a neural network parameterization.
