N2 - We show that tree-level "resonant" N-tachyon scattering amplitudes, which define a sensible "bulk" S-matrix in critical (super)string theory in any dimension, have a simple structure in two-dimensional space-time, due to partial decoupling of a certain infinite set of discrete states. We also argue that the general (non-resonant) amplitudes are determined by the resonant ones, and calculate them explicitly, finding an interesting analytic structure. Finally, we discuss the space-time interpretation of our results.
