【 摘 要 】

We set a combined limit on the effective Majorana neutrino mass mββfrom experimental searches for neutrinoless double-beta decay of multiple isotopes. The limits on mββrange between 130-310 meV, depending on the choice of nuclear matrix element calculation. The limits on mββcan also be translated into a limit on the neutrino mass and mixing parameters of a fourth sterile neutrino.
