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 pair. Our…

New insights from the flavor dependence of quark transverse momentum distributions in the pion

Lorenzo Rossi, Alessandro Bacchetta, Matteo Cerutti +1

We update our previous extraction of transverse momentum distributions of unpolarized quarks in the pion by implementing a more comprehensive description of theoretical uncertainti…

A Neural-Network Extraction of Unpolarised Transverse-Momentum-Dependent Distributions

Alessandro Bacchetta, Valerio Bertone, Chiara Bissolotti +4

We present the first extraction of transverse-momentum-dependent distributions of unpolarised quarks from experimental Drell-Yan data using neural networks to parametrise their non…

Exploring the three-dimensional momentum distribution of longitudinally polarized quarks in the proton

Alessandro Bacchetta, Alessia Bongallino, Matteo Cerutti +2

By analyzing experimental data on semi-inclusive deep inelastic scattering off longitudinally polarized targets, we extract the transverse momentum dependence of the quark helicity…

Proton 3D reconstruction with T-odd TMD gluon densities

Alessandro Bacchetta, Francesco Giovanni Celiberto, Marco Radici

We present studies aimed at probing the 3D gluon content of the proton through spin-dependent TMD gluon densities, computed by means of the spectator-model approach. Our formalism…

Flavor dependence of unpolarized quark Transverse Momentum Distributions from a global fit

Alessandro Bacchetta, Valerio Bertone, Chiara Bissolotti +6

We present an extraction of the unpolarized transverse-momentum-dependent parton distribution and fragmentation functions that takes into account possible differences between quark…
