Annihilation poles of a Smirnov-type integral formula for solutions to quantum Knizhnik--Zamolodchikov equation
arXiv:hep-th/9501138 · doi:10.1088/0305-4470/28/12/020
Abstract
We consider the recently obtained integral representation of quantum Knizhnik-Zamolodchikov equation of level 0. We obtain the condition for the integral kernel such that these solutions satisfy three axioms for form factor á la Smirnov. We discuss the relation between this integral representation and the form factor of XXZ spin chain.
