# Operator mixing and the BMN correspondence

@article{Constable2002OperatorMA, title={Operator mixing and the BMN correspondence}, author={Neil R. Constable and Daniel Z. Freedman and Matthew Headrick and Shiraz Minwalla}, journal={Journal of High Energy Physics}, year={2002}, volume={2002}, pages={068-068} }

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…
