Type 0 T-Duality and the Tachyon Coupling
arXiv:hep-th/0103244 · doi:10.1103/PhysRevD.64.126005
Abstract
We consider the T-duality relations between Type 0A and 0B theories, and show that this constraints the possible couplings of the tachyon to the RR-fields. Due to the `doubling' of the RR sector in Type 0 theories, we are able to introduce a democratic formulation for the Type 0 effective actions, in which there is no Chern-Simons term in the effective action. Finally we discuss how to embed Type II solutions into Type 0 theories.
