Using of unitarity equations for the calculation of fermion interaction amplitudes in the superstring theory
Abstract
The unitarity equations for the boson interaction amplitudes in the superstring theory are used to calculate the interaction amplitudes including the Ramond states, which are 10fermion and Ramond bosons. The nloop, 4point amplitude with two massless NeveuSchwarz bosons and two massless Ramond states is obtained explicitly. It is shown that, in addition, the unitarity equations require some integral relations for local functions determining the amplitude. For the tree amplitude the validness of the above integral relations is verified.
