Limits on cosmological variation of quark masses and strong interaction

arXiv:astro-ph/0209409 · doi:10.1103/PhysRevD.67.063513

Abstract

We discuss limits on variation of $(m_q/Λ_{QCD})$. The results are obtained by studying $n-α$-interaction during Big Bang, Oklo natural nuclear reactor data and limits on variation of the proton $g$-factor from quasar absorpion spectra.
