T-duality of O-plane action at order α′2
Abstract
We use compatibility of O-plane action with nonlinear T-duality as a guiding principle to find all NS-NS couplings in the O-plane action at order α′2. We find that the dilaton couplings appear in the string frame only via the transformation Rˆμν →Rˆμν +∇μ∇ν ϕ.
