New D1-D5-P geometries from string amplitudes
Stefano Giusto, Rodolfo Russo, David Turton
We derive the long range supergravity fields sourced by a D1-D5-P bound state from disk amplitudes for massless closed string emission. We suggest that since the parameter controll…
Classical Gravitational Observables from the Eikonal Operator
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
We propose two possible eikonal operators encoding the effects of classical radiation as coherent states of gravitons and show how to compute from them different classical observab…
Brane world effective actions for D-branes with fluxes
Matteo Bertolini, Marco Billo, Alberto Lerda +2
We develop systematic string techniques to study brane world effective actions for models with magnetized (or equivalently intersecting) D-branes. In particular, we derive the depe…
Matching the interaction at two-loops
Eric D'Hoker, Michael B. Green, Boris Pioline +1
The coefficient of the interaction in the low energy expansion of the two-loop four-graviton amplitude in type II superstring theory is known to be proportional to…
General Gauge Mediation in 5D
Moritz McGarrie, Rodolfo Russo
We use the "General Gauge Mediation" formalism to describe a 5D setup with an orbifold. We first consider a model independent SUSY breaking hidden sector on one bound…
The Eikonal Approach to Gravitational Scattering and Radiation at
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
Using supergravity as a theoretical laboratory, we extract the 3PM gravitational eikonal for two colliding massive scalars from the classical limit of the correspond…
