摘要：
We consider one-loop superstring amplitudes that are, in the large s and small t limit, down by one power of s with respect to the leading one. In the graviton-graviton scattering all contributions cancel. Instead, in the scattering of a massive scalar and a graviton, there exist contributions giving rise to quantum renormalizations as well as to the first non-linear (Schwarzschild-like) correction to Newton's law. © 1990.
