Assessing the Impact of Fitting Methodology at aNLO with FPPDF: an Open Source Tool for Extracting Parton Distribution Functions in the Hessian Approach
J. M. Cruz-Martinez, T. Giani, L. A. Harland-Lang
We present a new public code, FPPDF, to perform global fits of parton distribution functions (PDFs). The fitting methodology follows that implemented by the MSHT collaboration, nam…
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…
Neural-network analysis of Parton Distribution Functions from Ioffe-time pseudodistributions
Luigi Del Debbio, Tommaso Giani, Joseph Karpie +3
We extract two nonsinglet nucleon Parton Distribution Functions from lattice QCD data for reduced Ioffe-time pseudodistributions. We perform such analysis within the NNPDF framewor…
Parton distributions from lattice data: the nonsinglet case
Krzysztof Cichy, Luigi Del Debbio, Tommaso Giani
We revise the relation between Parton Distribution Functions (PDFs) and matrix elements computable from lattice QCD, focusing on the quasi-Parton Distribution Functions (qPDFs) app…
