Scattering Ripples from Branes
A novel probe of D-brane dynamics is via scattering of a high energy ripple traveling along an attached string. The inelastic processes in which the D-brane is excited through emission of an additional attached string is considered. Corresponding amplitudes can be found by factorizing a one-loop amplitude derived in this paper. This one-loop amplitude is shown to have the correct structure, but...

متن کاملScattering of Strings from D-branes
We review a number of perturbative calculations describing the interactions of D-branes with massless elementary string states. The form factors for the scattering of closed strings off D-branes are closely related to the Veneziano amplitude. They show that, in interactions with strings, D-branes acquire many of their physical features: the effective size of D-branes is of order the string scal...
متن کاملPlanckian Scattering of D - Branes
We consider the gravitational scattering of point particles in four dimensions, at Planckian centre of mass energy and low momentum transfer, or the eikonal approximation. The scattering amplitude can be exactly computed by modelling point particles by very generic metrics. A class of such metrics are black hole solutions obtained from dimensional reduction of p-brane solutions with one or more...
متن کاملScattering of Gauge, Matter, and Moduli Fields from Intersecting Branes
We calculate various tree–level (disk) scattering amplitudes involving gauge, matter and moduli fields in type IIB toroidal orbifold/orientifold backgrounds with D9, D5 respectively D7, D3–branes or via T -duality D6–branes in type IIA compactifications. In type IIB the D–branes may have non–vanishing fluxes on their world–volume. From these results we extract the moduli and flux dependence of ...
