Polarization Effects in Standard Model Parton Distributions at Very High Energies

TL;DR

This paper advances the understanding of Standard Model parton distribution functions by incorporating gauge boson polarization, electroweak boson PDFs, and NLO resummation, crucial for high-energy collider predictions.

Contribution

It introduces a comprehensive update to parton distribution functions including polarization effects, electroweak bosons, and higher-order resummation techniques.

Findings

Enhanced accuracy of PDFs at very high energies.

Inclusion of gauge boson polarization effects.

Implementation of next-to-leading-order resummation.

Abstract

We update the earlier work of Refs. arXiv:1703.08562 and arXiv:1712.07147 on parton distribution functions in the full Standard Model to include gauge boson polarization, non-zero input electroweak boson PDFs and next-to-leading-order resummation of large logarithms.
