Recent constraints on the parton distributions in the proton and the measurement of $\alpha_S$ from ATLAS and CMS

TL;DR

This paper reviews recent experimental results from ATLAS and CMS on processes sensitive to proton parton distributions, discussing their implications for refining PDFs and measuring the strong coupling constant, α_S.

Contribution

It provides an overview of recent collider data impacting the determination of proton PDFs and the measurement of α_S, highlighting new experimental constraints and their integration into global fits.

Findings

New jet and vector boson production data constrain PDFs.

Data influence the precision of α_S measurements.

Impacts on future PDF and α_S determinations.

Abstract

Recent results on cross sections sensitive to the parton distribution functions (PDFs) within the proton from the ATLAS and CMS Collaborations are presented. The potential impact on the inclusion of these data in fits to the PDFs is discussed. Recent results from fits including the data from jet, or vector boson production from the ATLAS and CMS experiments are discussed.
