  In a previous paper, arXiv:1204.3096, we have shown that the fully dynamical
three-point correlation functions of BMN operators are identical at the tree
level in the planar limit of perturbative field theory and, on the string
theory side, calculated by means of the Dobashi-Yoneya three string vertex in
the Penrose limit. Here we present a one-loop calculation of the same quantity
both on the field-theory and string-theory side, where a complete identity
between the two results is demonstrated.
