Contribution

It provides an improved 3+1 neutrino oscillation fit incorporating recent data, offering updated predictions for neutrino mass observables.

Findings

Predicted effective neutrino mass in beta-decay: 0.1-0.7 eV

Predicted effective neutrino mass in neutrinoless double-beta-decay: 0.01-0.1 eV

Implications for upcoming neutrino mass experiments

Abstract

We present an upgrade of the 3+1 global fit of short-baseline neutrino oscillation data obtained with the addition of KARMEN and LSND nu_e-Carbon scattering data. We discuss the implications for the measurements of the effective neutrino mass in beta-decay and neutrinoless double-beta-decay experiments. We find respective predicted ranges of about 0.1-0.7 eV and 0.01-0.1 eV.
