First next-to-next-to-leading-order extraction of fragmentation functions for Lambda hyperons
Valerio Bertone, Alessia Bongallino, Amedeo Chiefa +2
We present MAPFF1.0_Lambda, the first global analysis at next-to-next-to-leading order in perturbative QCD of the collinear unpolarised fragmentation functions of Lambda hyperons.…

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…
