Accidentally safe extensions of the Standard Model

TL;DR

This paper explores extensions of the Standard Model that introduce new charged or colored particles, which are stable enough to evade detection in low-energy experiments but could be observed in high-energy collider detectors.

Contribution

It identifies a class of Standard Model extensions that are invisible to low-energy probes but feature stable charged or colored particles detectable at high energies.

Findings

New stable charged/colored states predicted

Invisible to low-energy indirect probes

Potential signatures at high-energy colliders

Abstract

We discuss a class of weak-scale extensions of the Standard Model which is completely invisible to low-energy indirect probes. The typical signature of this scenario is the existence of new charged and/or colored states which are stable on the scale of high-energy particle detectors.
