Title Integrable spin chain and operator mixing in N = 1,2 supersymmetric theories
Date 2004-04
Description We study operator mixing, due to planar one-loop corrections, for composite operators in D = 4 supersymmetric theories. We present some N = 1, 2 Yang-Mills and Wess-Zumino models, in which the planar one-loop anomalous dimension matrix in the sector of holomorphic scalars is identified with the Hamiltonian of an integrable quantum spin chain with SU(3) or SU(2) symmetry, even if the theory is away from the conformal points. This points to a more universal origin of the integrable structure beyond superconformal symmetry. We also emphasize the role of the superpotential in the appearance of the integrable structure. The computations of operator mixing in our examples by solving Bethe Ansatz equations show some new features absent in N = 4 SYM.
