Light Dilaton at Fixed Points and Ultra Light Scale Super Yang Mills

Understand

We investigate the infrared dynamics of a nonsupersymmetric SU(X) gauge theory featuring an adjoint fermion, Nf Dirac flavors and an Higgs-like complex Nf x Nf scalar which is a gauge singlet.

• We first establish the existence of an infrared stable perturbative fixed point and then investigate the spectrum near this point.
• We demonstrate that this theory naturally features a light scalar degree of freedom to be identified with the dilaton and elucidate its physical properties.
• We compute the spectrum and demonstrate that at low energy the nonperturbative part of the spectrum of the theory is the one of pure supersymmetric Yang-Mills.
