A relation between massive and massless string tree amplitudes
A relation between massive and massless string tree amplitudes
We uncover a relation between the scattering amplitudes of massive strings and the α′ 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 α′2 order.

Abstract
We uncover a relation between the scattering amplitudes of massive strings and the α′ 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 α′2 order.
