摘要

Hidden local gauge invariance for Osp(2, 1) spin chain is studied in the framework of the quantum inverse scattering method. It is found that this model admits an Abel U(1) gauge transformation and the energy spectrum is gauge invariant, whereas the eigenvectors and Bethe ansatz equations are explicitly gauge dependent.
