BMN operators and string field theory
Sep, 2002Citations per year
Abstract:
We extract from gauge theoretical calculations the matrix elements of the SYM dilatation operator. By the BMN correspondence this should coincide with the 3-string vertex of light cone string field theory in the pp-wave background. We find a mild but important discrepancy with the SFT results. If the modified O(g2) matrix elements are used, the O(g22) anomalous dimensions are exactly reproduced without the need for a contact interaction in the single string sector.Note:
