Abstract
In these notes we study integrable structures of conformal field theory with BCD symmetry. We realise these integrable structures as \( \mathfrak{gl} \)(1) affine Yangian “spin chains” with boundaries. We provide three solutions of Sklyanin KRKR equation compatible with the affine Yangian R-matrix and derive Bethe ansatz equations for the spectrum. Our analysis provides a unified approach to the integrable structures with BCD symmetry including superalgebras.
