VENEZIANO AMPLITUDES, SPIN CHAINS, AND STRING MODELS

Abstract

In a series of recently published papers, we reanalyzed the existing treatments of Veneziano and Veneziano-like amplitudes and the models associated with these amplitudes. In this work, we demonstrate that the already obtained new partition function for these amplitudes can be exactly mapped into that for the Polychronakos–Frahm spin chain model. This observation allows us to recover many of the existing string-theoretic models, including the most recent ones.
