22 Jul 2005 | | Journal: | Phys.Rev. D72 (2005) 053015 | | Subject: | hep-ph | | Abstract: | In the framework of the see-saw mechanism the normal hierarchy is favorable for the neutrino mass spectrum. For this spectrum we present a detailed calculation of the half-lives of neutrinoless double beta decay for several nuclei of experimental interest. The half-lives are evaluated by considering the most comprehensive nuclear matrix elements, which were obtained within the renormalized QRPA by the Bratislava-Caltech-Tuebingen group. The dependence of the half-lives on sin^2 theta_{13}$ and the lightest neutrino mass is studied. We present also the results of the calculations of the half-lives of neutrinoless double beta decay in the case of the inverted hierarchy of neutrino masses. | | Source: | arXiv, hep-ph/0507260 | | Services: | Forum | Review | PDF | Favorites | |
