Mass Screening in Modified Gravity
Gregory Gabadadze, Alberto Iglesias
Models of modified gravity introduce extra degrees of freedom, which for consistency with the data, should be suppressed at observable scales. In the models that share properties o…
Strong CP Problem with 10^{32} Standard Model Copies
Gia Dvali, Glennys R. Farrar
We show that a recently proposed solution to the Hierarchy Problem simultaneously solves the Strong CP Problem, without requiring an axion or any further new physics. Consistency o…
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…
Localization of Gauge Fields and Monopole Tunnelling
G. Dvali, H. B. Nielsen, N. Tetradis
We study the dynamical localization of a massless gauge field on a lower-dimensional surface (2-brane). In flat space, the necessary and sufficient condition for this phenomenon is…
Bubbles in the Self-Accelerating Universe
Keisuke Izumi, Kazuya Koyama, Oriol Pujolas +1
We revisit the issue of the stability in the Dvali-Gabadadze-Porrati model, by considering the nucleation of bubbles of the conventional branch within the self-accelerating branch.…
