APFEL: A PDF Evolution Library with QED corrections
Valerio Bertone, Stefano Carrazza, Juan Rojo
Quantum electrodynamics and electroweak corrections are important ingredients for many theoretical predictions at the LHC. This paper documents APFEL, a new PDF evolution package t…
Parton distributions with QED corrections
The NNPDF Collaboration, Richard D. Ball, Valerio Bertone +6
We present a set of parton distribution functions (PDFs), based on the NNPDF2.3 set, which includes a photon PDF, and QED contributions to parton evolution. We describe the impleme…
Theoretical issues in PDF determination and associated uncertainties
The NNPDF Collaboration, Richard D. Ball, Valerio Bertone +5
We study several sources of theoretical uncertainty in the determination of parton distributions (PDFs) which may affect current PDF sets used for precision physics at the Large Ha…
