Graviton oscillations in the two-brane world
We study the braneworld effective action in the two-brane RandallSundrum model. In the framework of this essentially-nonlocal action we reveal the origin of an infinite sequence of gravitational wave modes — the usual massless one as well as the tower of Kaluza-Klein massive ones. Mixing of the modes, which parametrically depends on the background value of the modulus of the extra dimension, ca...
متن کاملGraviton emission from a soft brane
Theories with compact extra spatial dimensions felt only by gravity are subject to direct experimental tests if the compactification volume is large. Estimates of high-energy collider observables induced by graviton radiation into extra dimensions are usually given assuming rigid branes. This may overestimate the accessibility of these theories. Brane fluctuations soften the coupling of gravito...
متن کاملM-Theory Brane as Giant Graviton and the Fractional Quantum Hall Effect
A small number of M-theory branes as giant gravitons in the M-theory sector of LLM geometry is studied as a probe. The abelian way shows that the low energy effective action for M-theory brane is exactly the 2d electron subject to a vertical magnetic field. We also briefly discuss the microscopic description of M2-brane giant graviton in this geometry, in the language of a combination of D0-bra...
متن کاملShortcuts for Graviton Propagation in a Six Dimensional Brane World Model
We consider a six dimensional brane world model with asymmetric warp factors for time and both extra spatial coordinates, y and z. We derive the set of differential equations governing the shortest graviton path and numerically solve it for AdS-Schwarzschild and AdSReissner-Nordström bulks. In both cases we derive a set of conditions for the existence of shortcuts in bulks with shielded singula...
متن کاملHawking Radiation of the Brane-Localized Graviton from a (4 + n)-dimensional Black Hole
Following the Regge-Wheeler algorithm, we derive a radial equation for the brane-localized graviton absorbed/emitted by the (4 + n)-dimensional Schwarzschild black hole. Making use of this equation the absorption and emission spectra of the brane-localized graviton are computed numerically. Existence of the extra dimensions generally suppresses the absorption rate and enhances the emission rate...
