Combination of aNLO PDFs and implications for Higgs production cross-sections at the LHC

Thomas Cridge, Lucian A. Harland-Lang, Jamie McGowan +14

We discuss how the two existing approximate NLO (aNLO) sets of parton distributions (PDFs) from the MSHT20 and NNPDF4.0 series can be combined for LHC phenomenology, both i…

An FONLL prescription with coexisting flavor number PDFs

Andrea Barontini, Alessandro Candido, Felix Hekhorn +2

We present a new prescription to account for heavy quark mass effects in the determination of parton distribution functions (PDFs) based on the FONLL scheme. Our prescription makes…

The Path to NLO Parton Distributions

The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +16

We extend the existing leading (LO), next-to-leading (NLO), and next-to-next-to-leading order (NNLO) NNPDF4.0 sets of parton distribution functions (PDFs) to approximate next-to-ne…

Photons in the proton: implications for the LHC

The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +16

We construct a set of parton distribution functions (PDFs), based on the recent NNPDF4.0 PDF set, that also include a photon PDF. The photon PDF is constructed using the LuxQED for…

The intrinsic charm quark valence distribution of the proton

Richard D. Ball, Alessandro Candido, Juan Cruz-Martinez +7

We provide a first quantitative indication that the wave function of the proton contains unequal distributions of charm quarks and antiquarks, i.e. a nonvanishing intrinsic valence…
