A relation between massive and massless string tree amplitudes

High Energy Physics - Theory 2023-11-22 v1

Abstract

We uncover a relation between the scattering amplitudes of massive strings and the α\alpha' expansion of the massless string amplitude at tree level. More precisely, the n-point tree amplitude of n-1 massless and one massive state is written as a linear combination of n+1 massless string amplitudes at the α2\alpha'^2 order.
