Looking for milli-charged particles with a new experiment at the LHC

TL;DR

This paper proposes a novel LHC experiment to search for milli-charged particles, covering previously unexplored charge and mass ranges, thus opening new avenues for beyond Standard Model physics exploration.

Contribution

It introduces a new experimental approach at the LHC that is sensitive to milli-charged particles in a largely unconstrained parameter space.

Findings

Potential sensitivity to charges between 10^{-3}e and 10^{-1}e

Mass range sensitivity from 0.1 to 100 GeV

Provides a new experimental window for beyond Standard Model physics

Abstract

We propose a new experiment at the Large Hadron Collider (LHC) that offers a powerful and model-independent probe for milli-charged particles. This experiment could be sensitive to charges in the range $10^{-3}e - 10^{-1}e$ for masses in the range $0.1 - 100$ GeV, which is the least constrained part of the parameter space for milli-charged particles. This is a new window of opportunity for exploring physics beyond the Standard Model at the LHC.
