Chasing beams and muon colliders

TL;DR

The paper proposes a novel collider approach using 'chasing beams' with different energies to produce well-collimated, high-energy muons, potentially improving collider efficiency and particle longevity.

Contribution

It introduces the 'chasing beam' collision scheme as an alternative method for muon production in colliders, emphasizing its advantages in beam collimation and particle lifetime.

Findings

Chasing beam collisions can produce well-collimated muons.

High-energy muons with longer lifetimes are achievable.

Potential improvements in collider performance are suggested.

Abstract

A possible alternative way of producing muons (or other unstable particles) for colliders is proposed. It consists in colliding beams in a "chasing beam" configuration, i.e. collisions of two beams having the same direction but with different energies. This would produce muons with a good collimation, having already a high energy from the beginning, and then a longer life.
