✦ Synopsis

The methods of lattice gauge theory may be applied to gauge theories besides QCD, in fact to any gauge group and any representation of matter fields (as long as the coupling is not chiral). Such theories are useful for model building beyond the Standard Model, for instance in technicolor models. We have carried out Monte Carlo simulations of the SU(3) gauge theory with color sextet fermions. Our result for its discrete beta function indicate an infrared fixed point that makes the theory conformal rather than confining. The lattice theory's phase diagram shows no separation of chiral and confinement scales, measured when the quark mass is nonzero.

The CP symmetry is not manifestly implemented for the local and doubler-free Ginsparg-Wilson operator in lattice chiral gauge theory. We precisely identify where the effects of this CP breaking appear.
