BMN operators and string field theory
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(g2 2) anomalous dimensions are exactly reproduce...
متن کاملHolography at string field theory level: Conformal three point functions of BMN operators
A general framework for applying the pp-wave approximation to holographic calculations in the AdS/CFT correspondence is proposed. By assuming the existence and some properties of string field theory (SFT) on AdS5 × S5 background, we extend the holographic ansatz proposed by Gubser, Klebanov, Polyakov and Witten to SFT level. We extract relevant information of assumed SFT on AdS5×S from its appr...
متن کامل1 Boundary String Field Theory at One - loop
We apply the boundary string field theory (BSFT) to a unstable D-brane system to study the open-closed string duality at one loop in the presence of the tachyon condensation. The partition function at one-loop level is calculated by using both open and closed string channels. We find that the results from two different channels coincide, thus the open-closed string duality holds even off-shell.
متن کاملObservables and Correlation Functions in OSp Invariant String Field Theory
We define BRST invariant observables in theOSp invariant closed string field theory for bosonic strings. We evaluate correlation functions of these observables and show that the S-matrix elements derived from them coincide with those of the light-cone gauge string field theory. e-mail: [email protected] e-mail: [email protected] e-mail: [email protected]
متن کاملPlanar plane - wave matrix theory at the four loop order : Integrability without BMN scaling
We study SU(N) plane-wave matrix theory up to fourth perturbative order in its large N planar limit. The effective Hamiltonian in the closed su(2) subsector of the model is explicitly computed through a specially tailored computer program to perform large scale distributed symbolic algebra and generation of planar graphs. The number of graphs here was in the deep billions. The outcome of our co...
