Gauged double field theory, current algebras and heterotic sigma models

A bstract We study the O ( D, D + n ) generalized metric and the gauge symmetries in the gauged double field theory (DFT) in view of current algebras and sigma models. We show that the O ( D, D + n ) generalized metric in the gauged DFT is consistent with the heterotic sigma models at the leading or...

Description
Summary:A bstract We study the O ( D, D + n ) generalized metric and the gauge symmetries in the gauged double field theory (DFT) in view of current algebras and sigma models. We show that the O ( D, D + n ) generalized metric in the gauged DFT is consistent with the heterotic sigma models at the leading order in the α ′-corrections. We then study the non-Abelian gauge symmetries and current algebras of heterotic string theories. We show that the algebras exhibit the correct diffeomorphism, the B -field gauge transformations of the background fields together with the non-Abelian gauge transformations possibly with the appropriate local Lorentz transformations.
