Conformal Field Theory with background H-flux and T-dualityRalph Blumenhagen1, •Andreas Deser1, Dieter Lüst1,2, Erik Plauschinn3, and Felix Rennecke11Max-Planck-Institut für Physik, Föhringer Ring 6, 80805 München — 2Arnold Sommerfeld Center for Theoretical Physics, LMU, Theresienstr. 37, 80333 München — 3Institute for Theoretical Physics and Spinoza Institute, Utrecht University, 3508 TD Utrecht

We consider closed bosonic string theory with flat background and constant H-flux. Up to linear order in the flux, this is a solution to the string equations of motion and we are able to define a world-sheet conformal field theory framework to compute scattering amplitudes. In the easiest cases of n-point tachyon amplitudes, we use the properties of the Rogers dilogarithm function to speculate about the nature of the product of functions on spacetimes T-dual to the original configuration.
