(Quasi)Localized Gauge Field on a Brane: Dissipating Cosmic Radiation to Extra Dimensions?
G. Dvali, G. Gabadadze, M. Shifman
We propose a mechanism ensuring (quasi)localization of massless gauge fields on a brane. The mechanism does not rely on BPS properties of the brane and can be realized in any theor…
Gravity on a Brane in Infinite-Volume Extra Space
Gia Dvali, Gregory Gabadadze
We generalize the mechanism proposed in [hep-th/0005016] and show that a four-dimensional relativistic tensor theory of gravitation can be obtained on a delta-function brane in fla…
On Sub-Millimeter Forces From Extra Dimensions
Gia Dvali, Gregory Gabadadze, Massimo Porrati
We show that in theories with large extra dimensions forces mediated by a bulk dilaton and bulk gauge fields may be parametrically (exponentially) weaker than gravity due to the su…
4D Gravity on a Brane in 5D Minkowski Space
Gia Dvali, Gregory Gabadadze, Massimo Porrati
We suggest a mechanism by which four-dimensional Newtonian gravity emerges on a 3-brane in 5D Minkowski space with an infinite size extra dimension. The worldvolume theory gives ri…
Cosmological Constant and Fermi-Bose Degeneracy
G. Dvali
We study some cases in D=4 and in infinite-volume high dimensional theories when unbroken supersymmetry in the vacuum cannot guarantee Fermi-Bose degeneracy among excited states. I…
A Comment on Brane Bending and Ghosts in Theories with Infinite Extra Dimensions
G. Dvali, G. Gabadadze, M. Porrati
Theories with infinite volume extra dimensions open exciting opportunities for particle physics. We argued recently that along with attractive features there are phenomenological d…
