Constraining MeV to 10 GeV majoron by Big Bang Nucleosynthesis

Sanghyeon Chang, Sougata Ganguly, Tae Hyun Jung +2

We estimate the Big Bang nucleosynthesis (BBN) constraint on the majoron in the mass range between $1\mathrm{MeV}$ to $10\mathrm{GeV}$ which dominantly decays into the standard model…
