Description
The dynamics of systems governed by SU(N) gauge theory in presence
of a heavy colour field source is investigated inside the conformal window. Precise results on the spectra and wave functions of bound states are derived by generalizing the QCD static potential for fermions in different representation of the colour group. In particular, we establish characteristic behavior of the mass spectrum as one approaches the lower boundary of the conformal window, providing a new quantitative estimate of its location. Moreover, we argue that the mass spectrum offers a new perspective on the mechanism of loss of conformality, in analogy to dimensional transmutation taking place in Defect Conformal Field Theories when the annihilation of defect-coupling fixed points occurs. Our results pave way for new strategies to study conformality of non-abelian gauge theories nonperturbatively using lattice simulations.
