Abstract

We present a lattice study of the phase transitions at zero and nonzero temperature for the SU(3)SU(3) gauge theory with a varying number of flavours NfN_f in the fundamental representation of the gauge group. We show that all results are consistent with a lower edge of the conformal window between Nf=8N_f=8 and Nf=6N_f=6. A lower edge in this interval is in remarkable agreement with perturbation theory and recent large-NN arguments. .
