Eta Fragmentation Functions Revisited
Christine A. Aidala, Devon A. Loomis, Ramiro Tomas Martinez +2
We revisit the extraction of parton-to-eta meson fragmentation functions at next-to-leading order accuracy in QCD in the light of the recent hadroproduction measurements in proton-…

NNLO Global Analysis of Polarized Parton Distribution Functions
Ignacio Borsa, Daniel de Florian, Rodolfo Sassot +2
We present a next-to-next-to-leading order (NNLO) global QCD analysis of the proton's helicity parton distribution functions (PDFs), the first of its kind. To obtain the distributi…

Pion Nuclear Fragmentation Functions Revisited
Matias Doradau, Ramiro Tomas Martinez, Rodolfo Sassot +1
We revisit the notion of nuclear parton-to-pion fragmentation functions at next-to-leading order accuracy as an effective description of hadroproduction in nuclear environments suc…
