D-brane scattering in IIB string theory and IIB matrix model Original Research Article

We consider two Dirichlet p-branes with lower dimensional brane charges and their scattering. We first calculate the cylinder amplitude of the open string with suitable boundary conditions. We compare this result with that in the 11B matrix model. We find agreement between them in the long distance, low velocity, or large field limit. We also find a way to investigate more general boundary conditions for the open string.
