Abstract

We propose SL(2,Z) (and SL(3,Z)) invariant conjectures for all R⁴ H^4g-4 couplings of Type IIB strings on R¹⁰ (and R⁸× T²), generalizing conjectures of Green and Gutperle (and Kiritsis and Pioline) for the R⁴ coupling. A strong check for our conjectures is that on T² at weak coupling, they reproduce the multiloop scattering amplitudes which had been previously computed using N=2 strings in the N=4 topological formalism. Applications to (p,q) string production in a background H field, generalizing Schwinger's computation for pair production in constant F field, are suggested.
