Impurity non-preserving 3-point correlators of BMN operators from PP-wave holography I: bosonic excitations Original Research Article

As a continuation of our previous works studying the holographic principle in the plane-wave limit, we discuss the 3-point correlation functions of BMN operators with bosonic excitations when impurities are not conserved. We show that our proposal for a holographic mapping between the conformal OPE coefficients of super-Yang–Mills theory and the 3-point vertex of the holographic string field theory is valid to the leading order in the large μ limit. Our results provide for the first time a direct holographic relation for the 3-point correlators of BMN operators including impurity non-preserving processes.
