We continue the study of heterotic non-Abelian Bogomolny-Prasad-Sommerfield (BPS) saturated flux tubes (strings). Previously, such solutions were obtained in $\mathrm{U}(N)$ gauge theories: $\mathcal{N}=2$ supersymmetric QCD deformed by superpotential terms $\ensuremath{\mu}{\mathcal{A}}^{2}$ breaking $\mathcal{N}=2$ supersymmetry down to $\mathcal{N}=1$. In these models one cannot consider the limit $\ensuremath{\mu}\ensuremath{\rightarrow}\ensuremath{\infty}$ which would eliminate adjoint fields: …
