Maths HEP Lunchtime Seminars: High energy scattering between D-branes and closed strings
11 February 2011 13:00 in CM221
We study the high-energy scattering of massless closed strings from a stack of N Dp-branes in Minkowski spacetime and show that an effective non-trivial metric emerges from the string amplitudes. By changing the energy, impact parameter and effective open string coupling, we are able to explore various interesting regimes and reproduce semi-classical expectations, including tidal-force excitations, even
beyond the leading-eikonal approximation.
