Testing Partonic Charge Symmetry at a High-Energy Electron Collider

TL;DR

This paper explores the potential to measure partonic charge symmetry violation at a high-energy electron collider by comparing neutrino and antineutrino production, finding the effect could be several percent and detectable.

Contribution

It proposes a novel method to measure partonic charge symmetry violation using electron collider charged-current reactions, with quantitative estimates of the expected CSV magnitude.

Findings

CSV effect could be several percent at the collider

The effect is larger than typical partonic CSV effects

Potential for experimental detection of CSV at high-energy colliders

Abstract

We examine the possibility that one could measure partonic charge symmetry violation (CSV) by comparing neutrino or antineutrino production through charged-current reactions induced by electrons or positrons at a possible electron collider at the LHC. We calculate the magnitude of CSV that might be expected at such a facility. We show that this is likely to be a several percent effect, substantially larger than the typical CSV effects expected for partonic reactions.
