摘要：

We study the properties of amplitudes in the closed string theory based on the N = 2 worldsheet supergravity. The one-loop correction to the three-point amplitude is computed and compared to the effective field theory result. We discuss the peculiar kinematics arising from the (2, 2) signature of the space-time and its role in the factorization properties of the amplitudes.
