چکیده
We study inhomogeneous multidimensional cosmological models with a higher dimensional space-time manifold M = M0 × ∏n i=1 Mi (n ≥ 1) under dimensional reduction to D0-dimensional effective models and show that small inhomogeneous excitations of the scale factors of the internal spaces near minima of effective potentials should be observable as massive scalar particles (gravitational excitons) in the external space-time.

متن کاملBounds on Extra Dimensions from Binary Pulsars
Evidence for gravitational radiation from binary pulsars places constraints on properties of “large” extra dimensions. The size of these extra dimensions must exceed about 37 AU for gravitational radiation to be emitted. Subject headings: string theory — gravitation — relativity Typeset using REVTEX
متن کاملGravitational Radiation from Ultra High Energy Cosmic Rays in Models with Large Extra Dimensions
The effects of classical gravitational radiation in models with large extra dimensions are investigated for ultra high energy cosmic rays (CRs). The cross sections are implemented into a simulation package (SENECA) for high energy hadron induced CR air showers. We predict that gravitational radiation from quasi-elastic scattering could be observed at incident CR energies above 109 GeV for a set...
