Constraints on Neutrino Parameters by Neutrinoless Double Beta Decay Experiments
نویسنده
چکیده
Allowed regions on the ml cos 2θ12 plane are extracted from results of neutrinoless double beta decay experiments. It is shown that 0.05 eV(0 eV)< ∼ml < ∼ 1.85 eV is obtained for the normal (inverted) hierarchy by using the LMA best fit parameters and the 0νββ result announced late last year, which is 0.05 eV ≤ 〈m〉ββ ≤ 0.84 eV with ±50 % uncertainty of the nuclear matrix elements.

Constraints on Neutrino Mixing Parameters By Observation of Neutrinoless Double Beta Decay
Assuming positive observation of neutrinoless double bata decay together with the CHOOZ reactor bound, we derive constraints imposed on neutrino mixing parameters, the solar mixing angle θ12 and the observable mass parameter 〈m〉β in single beta decay experiments. We show that 0.05 eV ≤ 〈m〉β ≤ 2 eV at the best fit parameters of the LMA MSW solar neutrino solution by requiring the range of the pa...
متن کاملConstraints on Neutrinoless Double Beta Decay from Neutrino Oscillation Experiments
We show that, in the framework of a general model with mixing of three Majorana neutrinos and a neutrino mass hierarchy, the results of the Bugey and Krasnoyarsk reactor neutrino oscillation experiments imply strong limitations for the effective Majorana mass | 〈m〉 | that characterizes the amplitude of neutrinoless double beta decay. We obtain further limitations on | 〈m〉 | from the data of the...
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 ...
متن کاملWhat can we learn from neutrinoless double beta decay experiments?
We assess how well next-generation neutrinoless double beta decay and normal neutrino beta decay experiments can answer four fundamental questions. ~1! If neutrinoless double beta decay searches do not detect a signal, and if the spectrum is known to be inverted hierarchy, can we conclude that neutrinos are Dirac particles? ~2! If neutrinoless double beta decay searches are negative and a next-...
متن کاملParticle Physics Implications of Neutrinoless Double Beta Decay∗
Neutrinoless double beta decay is a sensitive probe of the patterns of neutrino masses and mixings if the neutrinos are Majorana particles as well as other new physics scenarios beyond the standard model. In this talk, the present experimental lower bound on the lifetime for ββ0ν is used to constrain the neutrino mixings and set limits on the parameters of the new physics scenarios such as the ...
