# Standard Model Parton Distributions at Very High Energies

## TL;DR

This paper calculates the evolution of all Standard Model parton distribution functions at very high energies, revealing significant effects on parton luminosities relevant for future 100 TeV collider experiments.

## Contribution

It provides the first comprehensive leading-order evolution of all 52 Standard Model PDFs across all interactions at energies far above the electroweak scale.

## Key findings

- Significant corrections to parton luminosities at 100 TeV energies.
- Numerical effects on PDFs at very high energies.
- Inclusion of all Standard Model interactions in PDF evolution.

## Abstract

We compute the leading-order evolution of parton distribution functions for all the Standard Model fermions and bosons up to energy scales far above the electroweak scale, where electroweak symmetry is restored. Our results include the 52 PDFs of the unpolarized proton, evolving according to the SU(3), SU(2), U(1), mixed SU(2) x U(1) and Yukawa interactions. We illustrate the numerical effects on parton distributions at large energies, and show that this can lead to important corrections to parton luminosities at a future 100 TeV collider.
