High Energy String Collisions in a Compact Space

Abstract

When high energy strings scatter at fixed angle, their amplitudes characteristically fall off exponentially with energy, $\mathcal{A}\sim \exp (-s\times const.)$. We show that in a compact space this suppression disappears for certain kinematic configurations. Amplitudes are power-law behaved and therefore greatly enhanced. In spacetime this corresponds to fixed-angle scattering, with fixed transfer in the compact dimensions. On the worldsheet this process is described by a stationary configuration of effective charges and vortices with vanishing total energy. It is worldsheet duality---and not spacetime duality---that plays a role.
