N2 - We present a detailed analysis of the domain walls in supersymmetric gluodynamics and SQCD. We use the (corrected) Veneziano-Yankielowicz effective Lagrangians to explicitly obtain the wall profiles and check recent results of Dvali and Shifman: (i) the BPS-saturated nature of the walls and (ii) the exact expressions for the wall energy density which depend only on global features of dynamics (the existence of a nontrivial central extension of [Formula presented] superalgebra in the theories which admit wall-like solutions). If supersymmetry is softly broken by the gluino mass, the degeneracy of the distinct vacua is gone, and one can consider the decay rate of the “false” vacuum into the genuine one. We do this calculation in the limit of the small gluino mass. Finally, we comment on the controversy regarding the existence of [Formula presented] distinct chirally asymmetric vacua in [Formula presented] SUSY gluodynamics.
