A Guaranteed Discovery at Future Muon Colliders

Understand

The longstanding muon g-2 anomaly may indicate the existence of new particles that couple to muons, which could either be light (< GeV) and weakly coupled, or heavy (>> 100 GeV) with large couplings.

• If light new states are responsible, upcoming intensity frontier experiments will discover further evidence of new physics.
• However, if heavy particles are responsible, many candidates are beyond the reach of existing colliders.
• We show that, if the g-2 anomaly is confirmed and no explanation is found at low-energy experiments, a high-energy muon collider program is guaranteed to make fundamental discoveries about our universe.
