Illuminating the photon content of the proton within a global PDF analysis
Valerio Bertone, Stefano Carrazza, Nathan P. Hartland +1
Precision phenomenology at the LHC requires accounting for both higher-order QCD and electroweak corrections as well as for photon-initiated subprocesses. Building upon the recent…
Minimisation strategies for the determination of parton density functions
Stefano Carrazza, Nathan P. Hartland
We discuss the current minimisation strategies adopted by research projects involving the determination of parton distribution functions (PDFs) and fragmentation functions (FFs) th…
Machine learning challenges in theoretical HEP
Stefano Carrazza
In these proceedings we perform a brief review of machine learning (ML) applications in theoretical High Energy Physics (HEP-TH). We start the discussion by defining and then class…
The photon PDF determination within the xFitter framework
Francesco Giuli
The xFitter project (former HERAFitter project) is an open-source package that provides a framework for the determination of the parton distribution functions (PDFs) of the proton…
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…
