Parton distributions and lattice QCD calculations: a community white paper
Huey-Wen Lin, Emanuele R. Nocera, Fred Olness +29
In the framework of quantum chromodynamics (QCD), parton distribution functions (PDFs) quantify how the momentum and spin of a hadron are divided among its quark and gluon constitu…
Fragmentation functions of charged hadrons
Emanuele R. Nocera
I present a preliminary determination of the Fragmentation Functions (FFs) of unidentified charged hadrons at next-to-leading order in quantum chromodynamics. The analysis is based…
The PDFLattice2017 workshop: a summary report
Emanuele R. Nocera, Huey-Wen Lin, Fred Olness +2
The workshop on Parton Distributions and Lattice Calculations in the LHC era (PDFLattice2017) was hosted at Balliol College, Oxford (UK), from 22 to 24 March…
Constraining the gluon PDF at large x with LHC data
Emanuele R. Nocera, Maria Ubiali
The NNPDF collaboration has recently presented NNPDF3.1, a new determination of the parton distribution functions (PDFs) of the proton including a number of new data, some of which…
A determination of the fragmentation functions of pions, kaons, and protons with faithful uncertainties
Valerio Bertone, Stefano Carrazza, Nathan P. Hartland +2
We present NNFF1.0, a new determination of the fragmentation functions (FFs) of charged pions, charged kaons, and protons/antiprotons from an analysis of single-inclusive hadron pr…
Parton distributions from high-precision collider data
The NNPDF Collaboration, Richard D. Ball, Valerio Bertone +13
We present a new set of parton distributions, NNPDF3.1, which updates NNPDF3.0, the first global set of PDFs determined using a methodology validated by a closure test. The update…
