N2 - Testing the BMN correspondence at non-zero string coupling gs requires a one-loop string field theory calculation. At order gs 2, matrix elements of the light-cone string field theory hamiltonian between single-string states receive two contributions: the iterated cubic interaction, and a contact term {Q, Q̄} whose presence is dictated by supersymmetry. In this paper we calculate the leading large μp +α′ contribution from both terms for the set of intermediate states with two string excitations. We find precise agreement with the basis-independent order g22 results from gauge theory.
