A Four-Reggeon Vertex for ${\mathbf{Z}}_3$ Twisted Fermionic Fields

Abstract

Using operator sewing techniques we construct the Reggeon vertex involving four external ${\mathbf{Z}}_3$-twisted complex fermionic fields. Generalizing a procedure recently applied to the ordinary Ramond four-vertex, we deduce the closed form of the ${\mathbf{Z}}_3$ vertex by demanding it to reproduce the results obtained by sewing.
