Belyaev, V.I. Lebedev and S. Zhukov (Russian Science Centre Kurchatov Institute, Moscow, Russia | | Abstract: | The Heidelberg-Moscow experiment gives the most stringent limit on the Majorana neutrino mass. After 24 kg yr of data with pulse shape measurements, we set a lower limit on the half-life of the neutrinoless double beta decay in 76Ge of T_1/2 > 5.7 * 10^{25} yr at 90% C.L., thus excluding an effective Majorana neutrino mass greater than 0.2 eV. This allows to set strong constraints on degenerate neutrino mass models. | | Source: | arXiv, hep-ex/9902014 | | Services: | Forum | Review | PDF | Favorites | |
