  Twin Higgs (TH) models explain the absence of new colored particles
responsible for natural electroweak symmetry breaking (EWSB). All known
ultraviolet completions of TH models require some non-perturbative dynamics
below the Planck scale. We propose a supersymmetric model in which the TH
mechanism is introduced by a new asymptotically free gauge interaction. The
model features natural EWSB for squarks and gluino heavier than 2 TeV even if
supersymmetry breaking is mediated around the Planck scale, and has interesting
flavor phenomenology including the top quark decay into the Higgs and the up
quark which may be discovered at the LHC.
