The automated computation of tree-level and next-to-leading order differential cross sections, and their matching to parton shower simulations [PDF]
Journal of High Energy Physics, 2014 A bstractWe discuss the theoretical bases that underpin the automation of the computations of tree-level and next-to-leading order cross sections, of their matching to parton shower simulations, and of the merging of matched samples that differ by light ...

Parton interpretation and twist-4 parton distributions
Physics Letters B, 2021 Through explicit examples we show that twist-4 parton distributions have no parton interpretation in the sense that parton or partons inside a hadron can carry the momentum fraction x of the hadron with x>1 or x1.

Parton distributions from high-precision collider data [PDF]
European Physical Journal C, 2017 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.

New Generation of Parton Distributions with Uncertainties from Global QCD Analysis [PDF]
Journal of High Energy Physics, 2002 A new generation of parton distribution functions with increased precision and quantitative estimates of uncertainties is presented. This work signiflcantly extends previous CTEQ and other global analyses on two fronts: (i) a full treatment of available ...

Identification of Parton Pairs in a Dijet Event and Investigation of Its Effects on Dijet Resonance Search [PDF]
Advances in High Energy Physics, 2014 Being able to distinguish parton pair type in a dijet event could significantly improve the search for new particles that are predicted by the theories beyond the Standard Model at the Large Hadron Collider.

A First Determination of Parton Distributions with Theoretical Uncertainties [PDF]
The European Physical Journal C, 2019 The parton distribution functions (PDFs) which characterize the structure of the proton are currently one of the dominant sources of uncertainty in the predictions for most processes measured at the Large Hadron Collider (LHC).

How Bright is the Proton? A Precise Determination of the Photon Parton Distribution Function [PDF]
Physical Review Letters, 2016 It has become apparent in recent years that it is important, notably for a range of physics studies at the Large Hadron Collider, to have accurate knowledge on the distribution of photons in the proton. We show how the photon parton distribution function

Parton Showering with Higher Logarithmic Accuracy for Soft Emissions. [PDF]
Physical Review Letters, 2023 The accuracy of parton-shower simulations is often a limiting factor in the interpretation of data from high-energy colliders. We present the first formulation of parton showers with accuracy 1 order beyond state-of-the-art next-to-leading logarithms ...
