The Higgs mechanism in Finsler spacetimes

L. Sindoni

Finsler geometry has been recently re-discovered as an interesting possibility to describe spacetime geometry beyond Riemannian geometry. The most evident effect of this class of m…

Towards an S-matrix Description of Gravitational Collapse

D. Amati, M. Ciafaloni, G. Veneziano

Extending our previous results on trans-Planckian () scattering of light particles in quantum string-gravity we present a calculation of the corresponding S-matrix fr…

Tracing the gas at redshift 1.7-3.5 with the Lyman-alpha forest: the FLO approach

F. Saitta, V. D'Odorico, M. Bruscoli +3

[Abridged] We present FLO (From Lines to Over-densities), a new technique to reconstruct the hydrogen density field for the Lya forest lines observed in high resolution QSO spectra…

Fate of gravitational collapse in semiclassical gravity

Carlos Barcelo, Stefano Liberati, Sebastiano Sonego +1

While the outcome of gravitational collapse in classical general relativity is unquestionably a black hole, up to now no full and complete semiclassical description of black hole f…

GRB 070724B: the first Gamma Ray Burst localized by SuperAGILE and its Swift X-ray Afterglow

E. Del Monte, M. Feroci, L. Pacciani +51

GRB 070724B is the first Gamma Ray Burst localized by SuperAGILE, the hard X-ray monitor aboard the AGILE satellite. The coordinates of the event were published hours aft…

On the stability of thick brane worlds non-minimally coupled to gravity

A. A. Andrianov, Luca Vecchi

We analyze a class of 5D models where a 3 brane is generated by a bulk scalar field non minimally coupled to gravity. We show that perturbative stability of such branes is normally…
