UCL cosmologists weigh into the debate about neutrino mass

11 August 2014

The standard model of particle physics needs to be extended: it predicts that neutrinos have zero mass, but this does not fit with experimental data. Recent work has suggested an unexpectedly high mass for the neutrino, but UCL cosmologists say this is wrong. They argue that a low mass is more consistent with the observed properties of the universe. The Dark Energy Survey (which UCL is also involved in) will provide data that could resolve this debate in the next few years.
