Query: Composite Higgs model at a conformal fixed point   We propose to construct a chirally broken model based on the infrared fixed
point of a conformal system by raising the mass of some flavors while keeping
the others massless. In the infrared limit the massive fermions decouple and
the massless fermions break chiral symmetry. The running coupling of this
system "walks" and the energy range of walking can be tuned by the mass of the
heavy flavors. Renormalization group considerations predict that the spectrum
of such a system shows hyperscaling.
  We have studied a model with four light and eight heavy flavors coupled to
SU(3) gauge fields and verified the above expectations. We determined the mass
of several hadronic states and found that some of them are in the 2-3 TeV range
if the scale is set by the pseudoscalar decay constant $F_\pi \approx 250$ GeV.
The $0^{++}$ scalar state behaves very differently from the other hadronic
states. In most of our simulations it is nearly degenerate with the pion and we
estimate its mass to be less than half of the vector resonance mass.
