Z' Bosons and Kaluza-Klein Excitations at Muon Colliders

After an extremely brief overview of the discovery reach for Z’ bosons, we will discuss the physics of Kaluza-Klein(KK) excitations of the Standard Model gauge bosons that can be explored by a high energy muon collider in the era after the LHC and TeV Linear Collider. We demonstrate that the muon collider is a necessary ingredient in the unraveling the properties of such KK states and, perhaps, proving their existence.
