# Achiral boundaries and the twisted Yangian of the D5-brane

@article{Mackay2011AchiralBA, title={Achiral boundaries and the twisted Yangian of the D5-brane}, author={Niall J. Mackay and Vidas Regelskis}, journal={Journal of High Energy Physics}, year={2011}, volume={2011}, pages={1-22} }

We consider integrable field theories with achiral boundary conditions and uncover the underlying achiral twisted Yangian algebra. This construction arises from old work on the bosonic principal chiral model on a half-line, but finds a modern realization as the hidden symmetry in the planar limit of the scattering of worldsheet excitations of the AdS/CFT light-cone superstring off a D5-brane.
