We discuss the physics of Kaluza-Klein 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 states and, perhaps, proving their existence. The possibility of observing the resonances associated wit...

We review the capability of colliders to detect the virtual exchange of Kaluza-Klein towers of gravitons within the low scale quantum gravity scenario of Arkani-Hamed, Dimopoulos and Dvali.

Various precision determinations of the Fermi constant are compared. Included are muon and (leptonic) tau decays as well as indirect prescriptions employing α, mZ , mW , sin 2 θW (mZ)MS , Γ(Z → l+l−), and Γ(Z → νν̄) as input. Their good agreement tests the standard model at the ±0.1% level and provides stringent constraints on new physics. That utility is illustrated for: heavy neutrino mixing, ...
