On dilaton dependence of type II superstring action
arXiv:hep-th/9601109 · doi:10.1088/0264-9381/13/6/003
Abstract
The supersymmetric action of type IIA D=10 superstring in N=2a, D=10 supergravity background can be derived by double dimensional reduction of the action of supermembrane coupled to D=11 supergravity. We demonstrate that the background Ramond-Ramond fields appear in the resulting superstring action with an extra factor of exponential of the dilaton.
