Quantum Gravity Effects in Black Holes at the LHC (2006)
Alberghi, Gian Luigi, Casadio, Roberto, Tronconi, Alessandro
We study possible back-reaction and quantum gravity effects in the evaporation of black holes which could be produced at the LHC through a modification of the Hawking emission. The corrections are...
Planck scale inflationary spectra from quantum gravity (2006)
Alberghi, Gian Luigi, Casadio, Roberto, Tronconi, Alessandro
We derive the semiclassical evolution of massless minimally coupled scalar matter in the de Sitter space-time from the Born-Oppenheimer reduction of the Wheeler-DeWitt equation. We show that the...
Ultra High Energy Cosmic Rays and de Sitter Vacua (2003)
Alberghi, Gian Luigi, Goldstein, Kevin, Lowe, David A.
The production of ultra high-energy cosmic rays in de Sitter invariant vacuum states is considered. Assuming the present-day universe is asymptoting toward a future de Sitter phase, we argue the...
Moduli Space Metric of N=2 Supersymmetric SU(N) Gauge Theory and the Enhancon (2002)
Alberghi, Gian Luigi, Corley, Steven, Lowe, David A.
We compute the moduli space metric of SU(N) Yang-Mills theory with N=2 supersymmetry in the vicinity of the point where the classical moduli vanish. This gauge theory may be realized as a set of N...
Stacking non-BPS D-Branes (2001)
Alberghi, Gian Luigi, Caceres, Elena, Goldstein, Kevin, Lowe, David A.
We present a candidate supergravity solution for a stacked configuration of stable non-BPS D-branes in Type II string theory compactified on T^4/Z_2. This gives a supergravity description of...
Charged False Vacuum Bubbles and the AdS/CFT Correspondence (1999)
Alberghi, Gian Luigi, Lowe, David A., Trodden, Mark
We initiate a study of cosmology within the framework of Maldacena's AdS/CFT correspondence. We present a comprehensive analysis of the classical motion of a charged domain wall that separates an...
