Abstract: We investigate the deformability of the Veneziano amplitude. If string theory is the unique theory of quantum gravity, the tree level amplitudes of weak coupling limits should be non-deformable. We make progress in this direction for tachyon-free superstring theories by deriving a general positivity bound and excluding some specific families of deformations.
