A novel approach to the study of conformality in the SU(3) theory with   multiple flavors
  We investigate the transition between spontaneous chiral symmetry breaking and conformal behavior in the SU(3) theory with multiple fermion flavors. We propose a new strategy for studying this transition. Instead of changing the number of flavors, we lift the mass of a subset of the fermions, keeping the rest of the fermions near to the massless chiral limit in order to probe the transition.   Dedicated to the 60th birthday of Academician Valery Rubakov.
