Big Bang Nucleosynthesis hunts chameleon dark matter

Abstract We study the chameleon field dark matter, dubbed scalaron, in F (R) gravity in the Big Bang Nucleosynthesis (BBN) epoch.With an R 2-correction term required to solve the singularity problem for F (R) gravity, we first find that the scalaron dynamics is governed by the R 2 term and the chameleon mechanism in the early universe, which makes
