Non-analytic terms of string amplitudes from partial waves
Abstract We describe a general formalism based on the partial-wave decomposition to compute the iterative s-channel discontinuity of four-point amplitudes at any loop order. As an application, we focus on the low-energy expansions of type I and II superstring amplitudes. Besides providing new result...
