Non Pauli-Fierz Massive Gravitons
Gia Dvali, Oriol Pujolas, Michele Redi
We study general Lorentz invariant theories of massive gravitons. We show that, contrary to the standard lore, there exist consistent theories where the graviton mass term violates…
Gravity Cutoff in Theories with Large Discrete Symmetries
Gia Dvali, Michele Redi, Sergey Sibiryakov +1
We set an upper bound on the gravitational cutoff in theories with exact quantum numbers of large N periodicity, such as Z_N discrete symmetries. The bound stems from black hole ph…
Cascading DGP
Claudia de Rham, Gia Dvali, Stefan Hofmann +4
We present a higher codimension generalization of the DGP scenario which, unlike previous attempts, is free of ghost instabilities. The 4D propagator is made regular by embedding o…
Black Hole Bound on the Number of Species and Quantum Gravity at LHC
Gia Dvali, Michele Redi
In theories with a large number N of particle species, black hole physics imposes an upper bound on the mass of the species equal to M_{Planck}/\sqrt{N}. This bound suggests a nove…
Consistent Lorentz Violation in Flat and Curved Space
Gia Dvali, Oriol Pujolas, Michele Redi
Motivated by the severity of the bounds on Lorentz violation in the presence of ordinary gravity, we study frameworks in which Lorentz violation does not affect the spacetime geome…
Detuned Randall-Sundrum model: Radion Stabilization and Supersymmetry Breaking
Michele Redi
In this talk I describe the low energy effective theory of the (supersymmetric) Randall-Sundrum scenario with arbitrary brane tensions. The distance between the branes is stabilize…
