Resolving conclusions about the early Universe requires accurate nuclear measurements

Nature Reviews Physics volume 3, pages 231–232 (2021)Cite this article

Subjects

Nuclear physics experiments give reaction rates that, via modelling and comparison with primordial abundances, constrain cosmological parameters. The error bars of a key reaction, D(p,γ)3He, were tightened in 2020, revealing discrepancies between different analyses and calling for more accurate measurements of other reactions.
