Rotating strings in six-dimensional higher-derivative supergravity

We construct the first analytical rotating string solution in six-dimensional Einstein-Gauss-Bonnet supergravity, carrying both electric and magnetic charges. By embedding the known rotating string solution of the two-derivative theory into six-dimensional off-shell supergravity, the Killing spinors associated with the underlying supersymmetry can be made off-shell and are universal to all off-shell supergravity models based on the same field content. The near-horizon geometry is ${\mathrm{S}}^3$ fibered over the extremal Bañados-Teitelboim-Zanelli black hole, locally isomorphic to ${\mathrm{AdS}}_3\times {\mathrm{S}}^3$. We compute the higher-derivative corrections to the Brown-Henneaux central charges in a particular $R+R^2$ model resulting from K3 compactification of type IIA string theory.
