Double Beta Decay

Neutrinoless reiterate of import decompose and neutrino physics arXiv:1206.2560v1 [hep-ph] 12 Jun 2012 Werner Rodejohann Max-Planck-Institut f¨r Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germ any u E-mail: werner.rodejohann@mpi-hd.mpg.de Abstract. The connection of neutrino physics with neutrinoless double over beta decay is reviewed. After presenting the current status of the PMNS matrix and the theoretical background of neutrino down and lepton mixture, we will summarize the non-homogeneous implications of neutrino physics for double beta decay. The in?uence of light unproductive neutrinos and other exotic modi?cations of the triplet neutrino picture is in any case discussed. Submitted to: Focus issue on Double beta decomposition in J. Phys.
