Abstract. We consider the quantum group invariant XXZmodel.
In infrared limit it describes Conformal Field Theory (CFT)
with modified energymomentum tensor. The correlation functions
are related to solutions of level 4 of qKZ equations. We describe
these solutions relating them to level 0 solutions. We further consider
general matrix elements (form factors) containing local operators
and asymptotic states. We explain that the formulae for solutions
of qKZ equations suggest a decomposition of these matrix
elements with respect to states of corresponding CFT.
