The status of the research on muon colliders is discussed and plans are outlined for future theoretical experimental studies. Besides continued work parameters a 3-4 0.5 TeV center-of-mass (CoM) energy collider, many studies now concentrating machine near 0.1 that could be factory s-channel production Higgs particles. We discuss various components in such colliders, starting from proton accelerator needed to generate pions heavy-Z target proceeding through phase rotation decay ($\pi \to \mu...
A muon collider represents the ideal machine to reach very high center-of-mass energies and luminosities by colliding elementary particles. This is result of low level beamstrahlung synchrotron radiation compared linear or circular electron-positron colliders. In contrast with other lepton machines, design a detector for multi-TeV requires detailed knowledge interaction region due significant backgrounds created beam decays in ring. The physics can be properly evaluated only when performance...

Present future experiments using large underground detectors, as well planned oscillation with free neutron beams are highlighted.
The physics goals of a Muon Collider (MC) can only be achieved with appropriate, self-consistent designs the ring, interaction region (IR), high-field superconducting magnets, machine-detector interface (MDI) and detector. Recent results from realistically-implemented simulation studies are presented here for 1.5-TeV MC. It is shown that if IR MDI designed appropriate shielding, background rates significantly suppressed in MC main characteristics these backgrounds also presented.
We propose the construction of, and describe in detail, a compact Muon Collider s-channel Higgs Factory.
Physics at a multi-TeV muon collider needs change of perspective for the detector design due to large amount background induced by beam decays.
