# Dimensional reduction of higher derivative heterotic supergravity

@inproceedings{Chang2021DimensionalRO, title={Dimensional reduction of higher derivative heterotic supergravity}, author={Hao‐Yuan Chang and Ergin Sezgin and Yoshiaki Tanii}, year={2021} }

Higher derivative couplings of hypermultiplets to $6D, N=(1,0)$ supergravity are obtained from dimensional reduction of 10D heterotic supergravity that includes order $\alpha'$ higher derivative corrections. Reduction on $T^4$ is followed by a consistent truncation. In the resulting action the hyperscalar fields parametrize the coset $SO(4,4)/(SO(4)\times SO(4))$. While the $SO(4,4)$ symmetry is ensured by Sen's construction based on string field theory, its emergence at the field theory level…
