Primordial Nucleosynthesis as a test of variable rest masses 5-dimensional cosmology

The deviation of primordial Helium production due to a variation on the difference between the rest masses of the nucleons is presented. It is found an upper bound δ(M<sub>n</sub>−M<sub>p</sub>)<∼0.129 MeV, between the present and nucleosynthesis epochs. This bound is used...

Sumario:The deviation of primordial Helium production due to a variation on the difference between the rest masses of the nucleons is presented. It is found an upper bound δ(M<sub>n</sub>−M<sub>p</sub>)<∼0.129 MeV, between the present and nucleosynthesis epochs. This bound is used to analyze Wesson’s theory of gravitation; as a result, it is ruled out by observation.
