Abstract

There is great interest within the particle physics community for building a μ+μ− collider with center-of-mass (CoM) energies ranging from s∼1–14  TeV. For beyond-the-Standard-Model (BSM) physics, natural supersymmetry seems perhaps the most motivated, plausible extension of the Standard Model. Here, we examine what can be accomplished by a muon collider with regards to natural SUSY at various muon collider CoM energies. In natural SUSY—especially in the guise that would emerge from the string landscape—one expects sparticles to be spread over two orders of magnitude in mass values. A muon collider with highly variable beam energies would be most useful for targeting 2-body reaction thresholds and Higgs boson resonances.
