Generalizing Frassek et al. (Adv. Math.401, 108283 (2022). https://doi.org/10.1016/j.aim.2022.108283), we construct a family ofSO(2r),Sp(2r),rational Lax matrices, polynomial in the spectral parameterz, parametrized by-valued divisorsDon. To this end, we provide the RTT realization of the antidominantly shifted extended Drinfeld Yangians of, and of their coproduct homomorphisms.
