WedgeLocal Fields in Integrable Models with Bound States
Abstract
Recently, large families of twodimensional quantum field theories with factorizing Smatrices have been constructed by the operatoralgebraic methods, by first showing the existence of observables localized in wedgeshaped regions. However, these constructions have been limited to the class of Smatrices whose components are analytic in rapidity in the physical strip. In this work, we construct candidates for observables in wedges for scalar factorizing Smatrices with poles in the physical strip and show that they weakly commute on a certain domain. We discuss some technical issues concerning further developments, especially the selfadjointness of the candidate operators here and strong commutativity between them.
