Query: Combined Constraints on Majorana Masses from Neutrinoless Double Beta
  Decay Experiments   Combined bounds on the Majorana neutrino mass for light and heavy neutrino
exchange mechanisms are derived from current neutrinoless double beta decay
(0{\nu}\b{eta}\b{eta}) search results for a variety of nuclear matrix element
(NME) models. The approach requires self-consistency of a given model to
predict NMEs across different isotopes. The derived bounds are notably stronger
than those from any single experiment and show less model-to-model variation,
highlighting the advantages of using multiple isotopes in such searches.
Projections indicate that the combination of near-term experiments should be
able to probe well into the inverted mass hierarchy region. A method to
visually represent 0{\nu}\b{eta}\b{eta} experimental results is also suggested
to more transparently compare across different isotopes and explicitly track
model dependencies.
