  • 摘要:I discuss the infrared behavior of the SU(3) gauge model with 12 fundamental fermions. Using a Monte Carlo renormalization group technique I investigate the fixed point structure in the chiral limit and show that this system has an infrared fixed point and consequently conformal infrared dynamics. I am able to reach the FP by using a new analysis method for the 2-lattice matching MCRG technique that significantly reduces finite volume effects and by choosing a lattice action that avoids a spurious ultraviolet fixed point created by strong coupling lattice artifacts.
