Findings

Proposes a mass-lifting technique to explore phase transitions.

Provides insights into the conformal window in SU(3) theories.

Suggests a new experimental approach for lattice studies.

Abstract

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.
