Query: Muon Collider   Both e+e- and {\mu}+{\mu}- colliders have been proposed as possible
candidates for a lepton collider to complement and extend the reach of the
Large Hadron Collider (LHC) at CERN. The physics program that could be pursued
by a new lepton collider (e+e- or {\mu}+{\mu}-) with sufficient luminosity
would include understanding the mechanism behind mass generation and
electroweak symmetry breaking; searching for, and possibly discovering,
supersymmetric particles; and hunting for signs of extra spacetime dimensions
and quantum gravity. However, the appropriate energy reach for such a collider
is currently unknown, and will only be determined following initial physics
results at the LHC. It is entirely possible that such results will indicate
that a lepton collider with a collision energy well in excess of 1 TeV will be
required to illuminate the physics uncovered at LHC. Such a requirement would
require consideration of muons as the lepton of choice for such a collider.
