Extraction of Dihadron Fragmentation Functions at NNLO with and without Neural Networks

Virgile Mahaut, Luca Polano, Alessandro Bacchetta +4

We present a new extraction of unpolarized Dihadron Fragmentation Functions, which describe the probability density for an unpolarized parton to fragment into a $\ddot{I}{€}^{+}\ddot{I}{€}^{-}$ pair. O…
