Extractions of the strong coupling from collider data without PDF refitting are biased
Stefano Forte, Juan Rojo, Roy Stegeman
We present an explicit demonstration that a determination of the strong coupling constant from deep-inelastic scattering and hadron collider data without a simultaneous…
A Determination of at Accuracy from a Global PDF Analysis
The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +6
We present a determination of the strong coupling from a global dataset including both fixed-target and collider data from deep-inelastic scattering and a variety of had…
NNPDFpol2.0: a global determination of polarised PDFs and their uncertainties at next-to-next-to-leading order
Juan Cruz-Martinez, Toon Hasenack, Felix Hekhorn +6
We present NNPDFpol2.0, a new set of collinear helicity parton distribution functions (PDFs) of the proton based on legacy measurements of structure functions in inclusive neutral-…
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…
Hyperparameter Optimisation in Deep Learning from Ensemble Methods: Applications to Proton Structure
Juan Cruz-Martinez, Aaron Jansen, Gijs van Oord +4
Deep learning models are defined in terms of a large number of hyperparameters, such as network architectures and optimiser settings. These hyperparameters must be determined separ…
NNPDF4.0 aNLO PDFs with QED corrections
Andrea Barontini, Niccolo Laurenti, Juan Rojo
We review recent progress in the global determination of the collinear parton distributions (PDFs) of the proton within the NNPDF framework. This progress includes NNPDF4.0 variant…
LO, NLO, and NNLO Parton Distributions for LHC Event Generators
Juan Cruz-Martinez, Stefano Forte, Niccolo Laurenti +2
We present NNPDF4.0MC, a variant of the NNPDF4.0 set of parton distributions (PDFs) at LO, NLO and NNLO, with and without inclusion of the photon PDF, suitable for use with Monte C…
Mapping the SMEFT at High-Energy Colliders: from LEP and the (HL-)LHC to the FCC-ee
Eugenia Celada, Tommaso Giani, Jaco ter Hoeve +5
We present SMEFiT3.0, an updated global SMEFT analysis of Higgs, top quark, and diboson production data from the LHC complemented by electroweak precision observables (EWPOs) from…
Heavy Quarks in Polarised Deep-Inelastic Scattering at the Electron-Ion Collider
Felix Hekhorn, Giacomo Magni, Emanuele R. Nocera +4
We extend the FONLL general-mass variable-flavour-number scheme to the case of longitudinally polarised DIS structure functions, accounting for perturbative corrections up to $\mat…
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…
Determination of the theory uncertainties from missing higher orders on NNLO parton distributions with percent accuracy
The NNPDF Collaboration, Richard D. Ball, Andrea Barontini +16
We include uncertainties due to missing higher order corrections to QCD computations (MHOU) used in the determination of parton distributions (PDFs) in the recent NNPDF4.0 set of P…
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…
The LHC as a Neutrino-Ion Collider
Juan M. Cruz-Martinez, Max Fieg, Tommaso Giani +4
Proton-proton collisions at the LHC generate a high-intensity collimated beam of neutrinos in the forward (beam) direction, characterised by energies of up to several TeV. The rece…
The automation of SMEFT-Assisted Constraints on UV-Complete Models
Jaco ter Hoeve, Giacomo Magni, Juan Rojo +2
The ongoing Effective Field Theory (EFT) program at the LHC and elsewhere is motivated by streamlining the connection between experimental data and UV-complete scenarios of heavy n…
