We present a new set of parton distribution functions (PDFs) based on a fully global dataset
and machine learning techniques: NNPDF4. 0. We expand the NNPDF3. 1 determination …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

This article documents the muon reconstruction and identification efficiency obtained by the
ATLAS experiment for 139 fb^-1 fb-1 of pp collision data at s= 13 s= 13 TeV collected …

A precise knowledge of the quark and gluon structure of the proton, encoded by the parton
distribution functions (PDFs), is of paramount importance for the interpretation of high …

A search is presented for four-top-quark production using an integrated luminosity of 139 fb^-
1-1 of proton–proton collision data at a centre-of-mass energy of 13~ TeV 13 TeV collected …

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 …

A summary of precision measurements sensitive to electroweak, QCD and quark-flavour
effects performed by the ATLAS Collaboration at the Large Hadron Collider is reported. The …

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 …

We present the computational framework Matrix (http://matrix. hepforge. org/) which allows
us to evaluate fully differential cross sections for a wide class of processes at hadron …
