Classic tests of General Relativity described by brane-based spherically symmetric solutions

摘要

We discuss a way to obtain information about higher dimensions from observations by studying a brane-based spherically symmetric solution. The three classic tests of General Relativity are analyzed in detail: the perihelion shift of the planet Mercury, the deflection of light by the Sun, and the gravitational redshift of atomic spectral lines. The braneworld version of these tests exhibits an additional parameter (b) related to the fifth-coordinate. This constant (b) can be constrained by comparison with observational data for massive and massless particles.
