Photon to axion conversion during Big Bang Nucleosynthesis
(IOP Publishing, 2023)We investigate how the resonant conversion at a temperature T¯=25-65 keV of a fraction of the CMB photons into an axion-like majoron affects BBN. The scenario, that assumes the presence of a primordial magnetic field and ...
