摘要：This proceeding is based on [1] where we study the spectrum of open strings localized at the intersections of D6-branes. For a regime in parameter space we find that the masses of the lightest states scale as M2 q qM2 s and can thus be parametrically smaller than the string scale. Relying on previous analyses, we compute scattering amplitudes of massless ‘twisted’ open strings and study their factorization, confirming the presence of the light massive states as sub-dominant poles in one of the channels. Along the analysis we provide a dictionary between states and their corresponding vertex operators.
