A number of arguments exists that the “minimal” Bogomol’nyi-Prasad-Sommerfeld (BPS) wall width in large-(Formula presented) supersymmetric gluodynamics vanishes as (Formula presented) There is a certain tension between this assertion and the fact that the mesons coupled to (Formula presented) have masses (Formula presented) To reconcile these facts we argue that there should exist additional solitonlike states with masses scaling as N. The BPS walls must be “made” predominantly of these heavy states which are coupled to (Formula presented) stronger than the conventional mesons. The tension of the BPS wall junction scales as (Formula presented) which serves as an additional argument in favor of the (Formula presented) scaling of the wall width. The heavy states can be thought of as solitons of the corresponding closed string theory. They are related to certain fivebranes in the M-theory construction. We study the issue of the wall width in toy models which capture some features of supersymmetric gluodynamics. We speculate that the special hadrons with mass scaling as N should also exist in the large-(Formula presented) limit of nonsupersymmetric gluodynamics.
