The PDFLattice2017 workshop: a summary report

TL;DR

The PDFLattice2017 workshop summarized recent progress and collaboration efforts between lattice-QCD and global-fit physicists to improve proton parton distribution functions for future high-precision experiments.

Contribution

This report highlights the integration of lattice calculations with global PDF fits and sets future precision targets for lattice QCD contributions.

Findings

Enhanced collaboration between lattice-QCD and global-fit communities.

Set of precision targets for lattice calculations.

Anticipation of a comprehensive white paper on the topic.

Abstract

The workshop on Parton Distributions and Lattice Calculations in the LHC era (PDFLattice2017) was hosted at Balliol College, Oxford (UK), from 22$^{\rm nd}$ to 24$^{\rm th}$ March 2017. The workshop brought together the lattice-QCD and the global-fit physicists who devote their efforts to determine the parton distribution functions (PDFs) of the proton. The goals were to make the two communities more familiar between each other, review developments from both sides, and set precision targets for lattice calculations so that they can contribute, together with the forthcoming experimental input, to the next generation of PDF determinations. This contribution summarises the relevant outcome of the workshop, in anticipation of a thorough white paper.
