# T-duality constraints on higher derivatives revisited

@article{Hohm2015TdualityCO, title={T-duality constraints on higher derivatives revisited}, author={Olaf Hohm and Barton Zwiebach}, journal={Journal of High Energy Physics}, year={2015}, volume={2016}, pages={1-27} }

A bstractWe ask to what extent are the higher-derivative corrections of string theory constrained by T-duality. The seminal early work by Meissner tests T-duality by reduction to one dimension using a distinguished choice of field variables in which the bosonic string action takes a Gauss-Bonnet-type form. By analyzing all field redefinitions that may or may not be duality covariant and may or may not be gauge covariant we extend the procedure to test T-duality starting from an action expressed…
