First Evidence for Neutrinoless Double Beta Decay
Double beta decay is indispensable to solve the question of the neutrino mass matrix together with ν oscillation experiments. Recent analysis of the most sensitive experiment since nine years the HEIDELBERG-MOSCOW experiment in Gran-Sasso yields a first indication for the neutrinoless decay mode. This result is the first evidence for lepton number violation and proves the neutrino to be a Major...
متن کاملNeutrinoless double beta decay
The status of the search for neutrinoless double beta decay is reviewed. The effort to reach the sensitivity needed to cover the effective Majorana neutrino mass corresponding to the degenerate and inverted mass hierarchy is described. Various issues concerning the theory (and phenomenology) of the relation between the 0νββ decay rate and the absolute neutrino mass scale are discussed, in parti...
متن کاملNeutrinoless Double-Beta Decay
This paper introduces the neutrinoless double-beta decay the rarest nuclear weak process and describes the status of the research for this transition, both from the point of view of theoretical nuclear physics and in terms of the present and future experimental scenarios. Implications of this phenomenon on crucial aspects of particle physics are briefly discussed. The calculations of the nuclea...
متن کاملConstraints from Neutrinoless Double Beta Decay
We examine the constraints from the recent HEIDELBERG-MOSCOW double beta decay experiment. It leads us to the almost degenerate or inverse hierarchy neutrino mass scenario. In this scenario, we obtain possible upper bounds for the Majorana CP violating phase in the lepton sector by incorporating the data from the neutrino oscillation, the single beta decay experiments, and from the astrophysica...
متن کاملNeutrinoless Double Beta Decay Constraints∗
A brief overview is given of theoretical analyses with neutrinoless double beta decay experiments. Theoretical bounds on the “observable”, 〈m〉ββ , are presented. By using experimental bounds on 〈m〉ββ , allowed regions are obtained on the ml-cos 2θ12 plane, where ml stands for the lightest neutrino mass. It is shown that Majorana neutrinos can be excluded by combining possible results of future ...
