Domain walls in supersymmetric QCD: The taming of the zoo
We provide a unified picture of the domain wall spectrum in supersymmetric QCD with N{sub c} colors and N{sub f} flavors of quarks in the (anti) fundamental representation. Within the framework of the Veneziano-Yankielowicz-Taylor effective Lagrangian, we consider domain walls connecting chiral symmetry breaking vacua, and we take the quark masses to be degenerate. For N{sub f}/N{sub c}<1/2, there is one BPS saturated domain wall for any value of the quark mass m. For 1/2{<=}N{sub f}/N{sub c}<1 there are two critical masses m{sub *} and m{sub **} which depend on the number of colors and flavors only through the ratio N{sub f}/N{sub c}. If m<m{sub *}, there are two BPS walls; if m{sub *}<m<m{sub **}, there is one non-BPS wall; and if m>m{sub **}, there is no domain wall. We numerically determine m{sub *} and m{sub **} as a function of N{sub f}/N{sub c}, and we find that m{sub **} approaches a constant value in the limit that this ratio goes to 1.
