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…

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…

The Noncommutative Geometry of the Quantum Projective Plane

Francesco D'Andrea, Ludwik Dabrowski, Giovanni Landi

We study the spectral geometry of the quantum projective plane CP^2_q, a deformation of the complex projective plane CP^2, the simplest example of a spin^c manifold which is not sp…

Remarks on confinement driven by axion-like particles in Yang-Mills theories

Patricio Gaete, Euro Spallucci

Features of screening and confinement are studied for a non-Abelian gauge theory with a mixture of pseudoscalar and scalar coupling, in the case where a constant chromo-electric, o…
