Abstract
We present a twistor-like formula for the complete tree-level S matrix of 6D supergravity coupled to abelian tensor multiplets. This is the low-energy effective theory that corresponds to Type IIB superstring theory compactified on a surface. The formula is expressed as an integral over the moduli space of certain rational maps of the punctured Riemann sphere. By studying soft limits of the formula, we are able to explore the local moduli space of this theory, . Finally, by dimensional reduction, we also obtain a new formula for the tree-level S matrix of 4D Einstein-Maxwell theory.
