Query: Bethe Ansatz equations and exact S matrices for the osp(M|2n) open super
  spin chain   We formulate the Bethe Ansatz equations for the open super spin chain based
on the super Yangian of osp(M|2n) and with diagonal boundary conditions. We
then study the bulk and boundary scattering of the osp(1|2n) open spin chain.
