Improved Big Bang Nucleosynthesis constraints on decaying massive relics
Sara Bianco, Jonas Frerick, Marco Hufnagel +1
We present updated and improved Big Bang Nucleosynthesis (BBN) constraints on heavy, long-lived beyond the Standard Model (BSM) relics decaying into pairs of Standard Model par…

Photo- and Hadrodisintegration constraints on massive relics decaying into neutrinos
Sara Bianco, Paul Frederik Depta, Jonas Frerick +3
We perform a detailed study of the cosmological constraints on the decay of a relic particle into neutrinos, , in particular those arising from the observe…
