String spectrum of curved string backgrounds obtained by T-duality and shifts of polar angles
Jorge G. Russo
A class of exactly solvable string models can be obtained by starting with flat space and combining T-duality and shifts of angular coordinates of several polar planes. The models…
Cosmological D-instantons and Cyclic Universes
E. A. Bergshoeff, A. Collinucci, D. Roest +2
For models of gravity coupled to hyperbolic sigma models, such as the metric-scalar sector of IIB supergravity, we show how smooth trajectories in the `augmented target space' conn…
Strong Magnetic Limit of String Theory
Jorge G. Russo
We show that there exists a certain limit in type I and type II superstring theory in the presence of a suitable configuration of magnetic U(1) fields where all string excitations…
Cross sections for production of closed superstrings at high energy colliders in brane world models
Diego Chialva, Roberto Iengo, Jorge G. Russo
In brane world string models with large extra dimensions, there are processes where fermion and antifermion (or two gluons) can annihilate producing a light particle (e.g. gluon) c…
The Information Problem in Black Hole Evaporation: Old and Recent Results
Jorge G. Russo
The formation and evaporation of a black hole can be viewed as a scattering process in Quantum Gravity. Semiclassical arguments indicate that the process should be non-unitary, and…
