It takes place as an alternative to Theoretical aspects of double beta decay Double beta decay (bb2n) is a second order weak nuclear decay that allows for even-even nuclei to decay by changing the atomic number by two units. Its discovery will prove the Majorana nature of neutrino (neutrino and anti-neutrino are the same state). References [29] and [30] contain pedagogical reviews of both the neutrino physics and the nuclear matrix elements that are relevant for ββ decay. Journal of Physics: Conference Series, The neutrinoless double beta decay is the most sensitive process to search the leptonic number violation in the neutrino sector. Abstract. Some nuclei can undergo double beta decay (ββ decay) where the charge of the nucleus changes by two units. An observation of this decay would show that neutrinos are Majorana particles and that lepton number is not always conserved.

Neutrino self-interactions ($\ensuremath{\nu}\mathrm{SI}$) beyond the Standard Model are an attractive possibility to soften cosmological constraints on neutrino properties and also to explain the tension in late and early time measurements of the Hubble expansion rate. It has been long recognized as a powerful tool for the study of lepton conservation in general and of neutrino properties in particular. It has been long recognized as a powerful tool for the study of lepton conservation in general and of neutrino properties in particular. Double Beta Decay Double Beta Decay Moe, M; Vogel, P 1994-12-01 00:00:00 Double beta ({3{3) decay is a rare transition between two nuclei with the same mass number that changes the nuclear charge number by two units . However, the existence of 0νββ-decay requires Majorana neutrino mass, no matter what the actual mechanism is. The obtained results from the first operational detectors are described. The most sensitive probe for the Majorana nature of neutrinos is an extremely rare nuclear decay process called neutrinoless double beta decay (\(0\nu \beta \beta \)), where a nucleus with mass number A and charge Z decays by emitting only two electrons and changes its charge by two units (A,Z)\(\longrightarrow \)(A,Z+2) + 2e\(^{-}\). The advancements in neutrinoless double beta decay search are presented. This paper will present the status of the running experiments (10 kg of ββ) emitter sources) as well as the projects of detectors for 100 kg of isotopes. Neutrinoless Double Beta Decay: 2015 Review . The pro-cess can be mediated by an exchange of a light Majorana neutrino, or by an exchange of other particles.

The double beta decay is a second order weak tran-sition which can be energetically favored for some even-even nuclei belonging to A even multiplets. We present results from the KamLAND-Zen double-beta decay experiment based on an exposure of 77.6 days with 129 kg of 136 Xe. You will only need to do this once. However, if the nucleus can also decay by single beta decay, , the branching ratio for the will be too difficult to be observed due to the overwhelming The discovery, principles, and current research on double beta decay are reviewed in Chapter 1, Volume 1. stream Two different types of experimental methods and … The double beta decay is a second order weak tran-sition which can be energetically favored for some even-even nuclei belonging to A even multiplets. In particular, we describe in some detail the only two cases in which the transition has been observed; that is the 2b +(0+!0 1) decay of 100Mo and 150Nd nuclides. %�쏢 The nEXO collaboration is currently designing a 5-ton liquid-xenon time projection chamber to search for neutrinoless double beta decay. Published under licence by IOP Publishing Ltd Review of neutrinoless double beta decay experiments Matteo Biassoni 1. • Critical for understanding incorporation of mass into standard model 5 0 obj Theoretical aspects of double beta decay Double beta decay (bb2n) is a second order weak nuclear decay that allows for even-even nuclei to decay by changing the atomic number by two units. Abstract: In this paper we review results obtained in the searches of double beta decays to excited states of the daughter nuclei and illustrate the related experimental techniques. The discovery of neutrino masses through the observation of oscillations boosted the importance of neutrinoless double beta decay (0 nu beta beta). Its discovery will prove the Majorana nature of neutrino (neutrino and anti-neutrino are the same state). In recent years, several review papers concerning neutrinoless double beta decay have been written. You do not need to reset your password if you login via Athens or an Institutional login. The ECEC(0ν) transitions to the excited states are discussed in association with a possible enhancement of the decay rate by several orders of magnitude.
