Temporal variation of coupling constants and nucleosynthesis
arXiv:astro-ph/0210459 · doi:10.1016/S0375-9474(03)00933-3
Abstract
We investigate the triple-alpha process and the Oklo phenomenon to obtain constraints on possible cosmological time variations of fundamental constants. Specifically we study cosmological temporal constraints for the fine structure constant and nucleon and meson masses.
