T-duality constraint on R-R couplings
Mohammad R. Garousi
It has been speculated that the metric, -field and dilaton couplings in the low energy effective action of string theory at any order of may be found by imposing the gauge…
Surface terms in the effective actions via duality constraints
Mohammad R. Garousi
The effective action of string theory on a spacetime manifold with boundary has both bulk and boundary terms. We propose that both bulk and boundary actions, may be found by imposi…
Effective action of bosonic string theory at order
Mohammad R. Garousi
Recently, it has been shown that the gauge invariance requires the minimum number of independent couplings for -field, metric and dilaton at order to be 60. In this paper…
Four-derivative couplings via T-duality constraint
Mohammad R. Garousi
We examine the proposal that the dimensional reduction of the effective action of perturbative string theory on a circle, should be invariant under T-duality transformations. The T…
Minimal independent couplings at order
Mohammad R. Garousi, Hamid Razaghian
Using field redefinitions and Bianchi identities on the general form of the effective action for metric, -field and dilaton, we have found that the minimum number of independent…
