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.…

Gluon Sivers function in dijet production at the EIC
Miguel G. Echevarria, Patricia Andrea Gutierrez GarcÃa, Patricia Andrea Gutierrez García +1
The transverse-momentum-dependent (TMD) factorization theorem for dijet production in deep-inelastic scattering is used here to make predictions of the gluon Sivers function. We re…

Factorization for leptoproduction at small transverse momentum
Miguel G. Echevarria, Samuel F. Romera, Pieter Taels
Nonrelativistic Quantum Chromodynamics (NRQCD) breaks down in the region of low transverse momentum, where the transverse momentum of the produced quarkonium state is sensitive to…
