Tenacious Domain Walls in Supersymmetric QCD

TL;DR

This paper analyzes the structure of stable BPS domain walls in supersymmetric QCD with large matter field masses, revealing a three-layer configuration with energy distribution depending on flavor number and field windings.

Contribution

It provides a detailed description of the layered structure of tenacious domain walls in supersymmetric QCD, highlighting their composition and energy distribution.

Findings

Domain walls have a three-layer structure: coat, core, and outer layers.

The core's width is inversely proportional to the matter field mass.

The energy fraction in the core varies with flavor number and field windings.

Abstract

We study the structure of the tenacious (existing for all values of masses of the matter fields) BPS domain walls interpolating between different chirally asymmetric vacua in supersymmetric QCD in the limit of large masses. We show that the wall consists in this case of three layers: two outer layers form a ``coat'' with the characteristic size determined by \Lambda_{SYM} and there is also the core with width of order of inverse mass. The core always carries a significant fraction of the total wall energy. This fraction depends on $N_f$ and on the ``windings'' of the matter fields.
