摘要：Yang-Mills theory is known to exhibit very different behavior as the number of light fermion
flavors Nf is varied. In particular, for sufficiently large Nf the theory changes fro confining to
conformal behavior in the infrared. We have obtained results for SU(3) Yang-Mills, based on the
study of the running coupling through the Schrödinger Functional approach, that the transition
between these two phases occurs between 8 and 12 flavors. I will present the details of our
staggered fermion simulations at Nf = 8 and 12.
