Abstract

This article continues 1205.0410 [hep-th]. Considered is the N=1 SQCD-like theory with SU(N_c) colors and 3N_c/2 <N_F <2N_c flavors of light quarks Q_i, Q_j, and with the additional N²_F colorless flavored fields Phi_ij with the large mass parameter μ_Phi>>Lambda. The mass spectra of this Phi theory (and its dual variant, the dPhi theory) are calculated at different values of μ_Phi/Lambda >>1 within the dynamical scenario which implies that quarks can be in two different phases only: either this is the HQ (heavy quark) phase where they are confined, or they are higgsed at appropriate values of the lagrangian parameters. It is shown that at the left end of the conformal window, i.e. at 0<(2N_F-3N_c)/N_F << 1, the mass spectra of the direct and dual theories are parametrically different.
