Query: Higher-derivative corrections to type II supergravity:Four Ramond-Ramond
  terms   It is known that the sphere-level S-matrix element of four type II
superstrings has one kinematic factor. At the low energy limit, this factor
produces the kinematic factor of the corresponding Feynman amplitudes in the
supergravity. It also produces higher-derivative couplings of four strings. In
this paper, we explicitly calculate the kinematic factor of four RR states in
the supergravity. Using this factor, we then find the eight-derivative P-even
and P-odd couplings of four RR fields, including the self-dual RR five-form
field strength. We show that the P-even couplings are mapped to the standard
$\bar{R}^4$ couplings by linear T-duality and S-duality transformations. We
also confirm the P-even couplings with direct calculations in type II
superstring theories.
