Scientific paper

With a moduli independent choice of super-Beltrami differentials, we show, by using the genus-two hyperelliptic formalism, that the requirement of modular invariance determines completely the two-loop amplitudes of the heterotic string theory for arbitrary external legs and that the cosmological constant is zero pointwise in moduli space.
