Still No Sign Of Neutrinoless Double Beta Decay

From here (arXiv 2207.07638).

Of course, we have good reason (from cosmology data and from the pattern of the neutrino mass differences in oscillation data) to think that the neutrino masses are smaller than the masses at which neutrinoless double beta decay ought to be possible to detect with existing experiments in any case, so the null result doesn't necessarily do much to shake the Majorana neutrino mass hypothesis yet.
