我们考虑量子群不变量XXZ模型。在红外极限，它描述了一个共形场论（CFT）与修改的能量动量张量。相关函数与qKZ方程的水平-4的解有关。我们将这些解决方案与0级解决方案相关联。我们进一步考虑包含局部算子和渐近状态的一般矩阵元素（形状因子）。我们解释说，qKZ方程的解决方案的公式建议这些矩阵元素的分解相对于相应的CFT的状态。
We consider the quantum group invariant XXZ-model. In the infrared limit it describes a Conformal Field Theory (CFT) with modified energy-momentum tensor. The correlation functions are related to solutions of level −4 of the 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 the qKZ equations suggest a decomposition of these matrix elements with respect to states of the corresponding CFT.
