Mass spectra in N=1 SQCD with additional fields. II

TL;DR

This paper analyzes the mass spectra of an N=1 SQCD-like theory with additional fields, revealing differences between direct and dual theories near the conformal window's edge, within a specific dynamical scenario.

Contribution

It calculates the mass spectra of the Phi theory and its dual at large F/Lambda, highlighting differences near the conformal window's boundary.

Findings

Mass spectra are parametrically different at the conformal window's edge.

Quarks are either confined or higgsed, depending on parameters.

The analysis extends previous work to include additional flavored fields.

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,\bar Q_j, and with the additional N^2_F colorless flavored fields Phi_{ij} with the large mass parameter \mu_Phi>>Lambda. The mass spectra of this Phi theory (and its dual variant, the dPhi theory) are calculated at different values of \mu_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.
