Abstract
Closed string dynamics in the presence of non-commutative Dp-branes is investigated. In particular, we compute bulk closed string two-point scattering amplitudes; the bulk space-time geometries encoded in the amplitudes are shown to be consistent with the recently proposed background space-time geometries dual to non-commutative Yang-Mills theories. Three-point closed string absorption/emission amplitudes are obtained to show some features of non-commutative Dp-branes, such as modified pole structures and exponential phase factors linearly proportional to the external closed string momentum.
