Gauged Double Field Theory, Current Algebras and Heterotic Sigma Models

Machiko Hatsuda, Haruka Mori, Shin Sasaki +1

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)…
