Description

Extending the TMD factorization to thrust-dependent observables entails difficulties ultimately associated with the behavior of soft radiation.
In this talk, the factorization properties of the thrust distribution of $e^+e^-$ annihilation into a single hadron are discussed and their peculiarities with respect to standard TMD factorization are highlighted.
I present the phenomenological extraction of the unpolarized TMD Fragmentation Function for pions, for the first time based on a sound factorization theorem that correctly takes into account the thrust dependence in the $2$-jet region.
