  Muon-based accelerators have the potential to enable facilities at both the
Intensity and the Energy Frontiers. Muon storage rings can serve as high
precision neutrino sources, and a muon collider is an ideal technology for a
TeV or multi-TeV collider. Progress in muon accelerator designs has advanced
steadily in recent years. In regard to 6D muon cooling, detailed and realistic
designs now exist that provide more than 5 order-of-magnitude emittance
reduction. Furthermore, detector performance studies indicate that with
suitable pixelation and timing resolution, backgrounds in the collider
detectors can be significantly reduced thus enabling high quality physics
results. Thanks to these and other advances in design and simulation of muon
systems, technology development, and systems demonstrations, muon
storage-ring-based neutrino sources and a muon collider appear more feasible
than ever before. A muon collider is now arguably among the most compelling
approaches to a multi-TeV lepton collider and an S-Channel Higgs Channel.
