Abstract
In this note we update the discussion of the BMN correspondence and string interactions in [4] to incorporate the effects of operator mixing. We diagonalize the matrix of two point functions of single and double trace operators, and compute the eigen-operators and their anomalous dimensions to order g22λ '. Operators in different R symmetry multiplets remain degenerate at this order; we propose this is a consequence of supersymmetry. We also calculate the corresponding energy shifts in string theory, and find a discrepancy with field theory results, indicating possible new effects in light-cone string field theory.
