Abstract

In this paper we continue the study of QQ-operators in the six-vertex model and its higher spin generalizations. In [1] we derived a new expression for the higher spin RR-matrix associated with the affine quantum algebra Uq(sl(2)^)U_q(\widehat{sl(2)}). Taking a special limit in this RR-matrix we obtained new formulas for the QQ-operators acting in the tensor product of representation spaces with arbitrary complex spin. Here we use a different strategy and construct QQ-operators as integral operators with factorized kernels based on the original Baxter's method used in the solution of the eight-vertex model. We compare this approach with the method developed in [1] and find the explicit connection between two constructions. We also discuss a reduction to the case of finite-dimensional representations with (half-) integer spins.
