What 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 کاملNeutrinoless double beta decay with scalar bilinears
One possible probe to physics beyond the standard model is to look for scalar bilinears, which couple to two fermions of the standard model. We point out that the scalar bilinears allow new diagrams contributing to the neutrinoless double beta decay. The upper bound on the neutrinoless double beta decay lifetime would then give new constraints on the ratio of the masses of these scalars to thei...

We fitted the neutrino oscillations, baryogenesis and neutrinoless double beta decay using Anti-GUT model.
متن کاملThe SuperNEMO Experiment
Double beta decay is a rare nuclear process in which two neutrons in the same nucleus are spontaneously converted into two protons. This process occurs when normal beta decay is either forbidden or suppressed, and may happen in at least two different ways: by the emission of two electrons and two anti-electron neutrinos (already observed in many nuclei), or possibly by the emission of two elect...
متن کاملModel-independent Constraint on the Neutrino Mass Spectrum from the Neutrinoless Double Beta Decay
We present a concise formula to relate the effective mass term of the neutrinoless double beta decay to a single neutrino mass, two Majorana CP-violating phases and four observables of neutrino oscillations for a generic neutrino mass spectrum. If the alleged evidence for the neutrinoless double beta decay is taken into account, one may obtain a rough but model-independent constraint on the abs...
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...
