| Muon colliders are under consideration as a possible important future energy-frontier accelerator. A muon collider could be built as a circular accelerator into the TeV energy range as a result of the reduced synchrotron radiation expected from the larger rest mass of muons. Unlike existing lepton (electron/positron) colliders, muons decay with a 2.2 microsecond lifetime. These decays will produce very energetic electrons off of the beam reference orbit which can generate detector backgrounds that can affect the physics. The main backgrounds include electrons from muon decays, synchrotron radiation from the decay electrons, hadrons produced by photonuclear interactions, coherent and incoherent beam-beam pair-production, and Bethe-Heitler muon production. We will discuss simulation results in terms of observed physics processes in G4beamline. |
