On Riemann curvature corrections to type II supergravity    [PDF]

Mohammad R. Garousi

We observe that the generalized Riemann curvature corrections to the type II supergravity which appear in the literature, are not fully consistent with the S-matrix elements in the superstring theory. In particular, they produce non-zero S-matrix elements for odd number of B-field strengths which are not consistent with the string theory results. We solve this problem by adding some new Riemann curvature couplings to the Lagrangian density.
