A sequential majoron-to-neutrinos decay followed by axion-like particle-to-photons decay can lower primordial lithium without exceeding deuterium limits.
Joint analysis of neutrino detectors and CMB observables can constrain dark matter annihilation into neutrinos for MeV-GeV masses.
Updated exclusion contours on lifetime, mass and abundance of decaying BSM relics from refined BBN modeling of hadronic and electromagnetic injections across multiple two-body channels.
