QCD with many light quark flavors may have a conformal phase, before the theory loses asymptotic freedom. We report on extensive simulations of 8 and 12 flavor QCD, where we have measured light hadron masses, decay constants and the string tension at zero temperature. We have also observed the finite temperature transition for 8 flavors and seen that it is first order. This data supports 8 and 12 flavor QCD being in the conventional, chirally broken phase, in contrast to other studies measuring the beta function.
