A microscopic description of absorption in high-energy string-brane collisions
Giuseppe D'Appollonio, Paolo Di Vecchia, Rodolfo Russo +1
We study the collision of a highly energetic light closed string off a stack of Dp-branes at (sub)string-scale impact parameters and in a regime justifying a perturbative treatment…
Infrared divergences and harmonic anomalies in the two-loop superstring effective action
Boris Pioline, Rodolfo Russo
We analyze the pertubative contributions to the and couplings in the low-energy effective action of type II string theory compactified on a torus , with pa…
AdS3 Holography for 1/4 and 1/8 BPS geometries
Stefano Giusto, Emanuele Moscato, Rodolfo Russo
Recently a new class of 1/8-BPS regular geometries in type IIB string theory was constructed in arXiv:1503.01463. In this paper we provide a precise description of the semiclassica…
Two-loop Yang-Mills diagrams from superstring amplitudes
Lorenzo Magnea, Sam Playle, Rodolfo Russo +1
Starting from the superstring amplitude describing interactions among D-branes with a constant world-volume field strength, we present a detailed analysis of how the open string de…
Habemus Superstratum! A constructive proof of the existence of superstrata
Iosif Bena, Stefano Giusto, Rodolfo Russo +2
We construct the first example of a superstratum: a class of smooth horizonless supergravity solutions that are parameterized by arbitrary continuous functions of (at least) two va…
Regge behavior saves String Theory from causality violations
Giuseppe D'Appollonio, Paolo Di Vecchia, Rodolfo Russo +1
Higher-derivative corrections to the Einstein-Hilbert action are present in bosonic string theory leading to the potential causality violations recently pointed out by Camanho et a…
