On the curious spectrum of duality invariant higher-derivative gravity
Olaf Hohm, Usman Naseer, Barton Zwiebach
We analyze the spectrum of the exactly duality and gauge invariant higher-derivative double field theory. While this theory is based on a chiral CFT and does not correspond to a st…

Three-point Functions in Duality-Invariant Higher-Derivative Gravity
Usman Naseer, Barton Zwiebach
Doubled -geometry is the simplest higher-derivative gravitational theory with exact global duality symmetry. We use the double metric formulation of this theory to compute on-s…
