JUNO and Neutrinoless Double Beta Decay

Understand

We study the impact of the precision determination of oscillation parameters in the JUNO experiment on half-life predictions for neutrinoless double beta decay.

• We show that the solar neutrino mixing angle can be measured by JUNO with below 1% uncertainty.
• This implies in particular that the minimal value of the effective mass in the inverted mass ordering will be known essentially without uncertainty.
• We demonstrate that this reduces the range of half-life predictions in order to test this value by a factor of two.
