Abstract
In 2005 Berenstein and Vázquez determined an open spin chain Hamiltonian describing the oneloop anomalous dimensions of determinantlike operators corresponding to open strings attached to Y = 0 maximal giant gravitons We construct the transfer ma trix generating functional of conserved quantities containing this Hamiltonian thereby directly proving its integrability We find the eigenvalues of this transfer matrix and the corresponding Bethe equations which we compare with proposed allloop Bethe equations We note that the Bethe ansatz solution has a certain “gauge” freedom and is not com pletely unique
