Abstract

We employ a discrete integral-reflection representation of the double affine Hecke algebra of type CCC^\vee C at the critical level q=1, to endow the open finite qq-boson system with integrable boundary interactions at the lattice ends. It is shown that the Bethe Ansatz entails a complete basis of eigenfunctions for the commuting quantum integrals in terms of Macdonald's three-parameter hyperoctahedral Hall-Littlewood polynomials.
