Neutron lifetime anomaly and Big Bang nucleosynthesis
Tammi Chowdhury, Seyda Ipek
Abstract
We calculate the Big Bang nucleosynthesis abundances for helium-4 and deuterium for a range of neutron lifetimes, τ n = 840–1050 s, using the state-of-the-art Python package PRyMordial. We show the results for two different nuclear reaction rates, calculated by NACRE II and the PRIMAT collaborations.
