Non-geometric fluxes, asymmetric strings and nonassociative geometry
Non-geometric fluxes, asymmetric strings and nonassociative geometry
We study closed bosonic strings propagating both in a flat background with constant H-flux and in its T-dual configurations. We define a conformal field theory capturing linear effects in the flux and compute scattering amplitudes of tachyons, where the Rogers dilogarithm plays a prominent role. For the scattering of four …
