Status and Results from the EXO Collaboration
EPJ Web of Conferences, 2014 The Enriched Xenon Observatory (EXO) is an experimental program searching for neutrinoless double-beta decay using 136Xe. Such a search can shed light on the Majorana nature of the neutrino (whether the neutrino is its own anti-particle), the absolute ...

On neutrinoless double beta decay in the νMSM
Physics Letters B, 2016 We consider the neutrinoless double beta (0νββ) decay in the νMSM, in which three right-handed neutrinos with masses below the electroweak scale are additionally introduced to the Standard Model. In this model there appear three heavy neutral leptons N1,

Double beta decay: Calorimeters
Journal of Physics: Conference Series, 2008 Calorimeters or, with a more specific definition, low temperature detectors, have been used by now for more than 15 years in Double Beta Decay (DBD) searches, with excellent results: they compete with Ge diodes for the rank of detectors with the highest sensitivity to the effective neutrino mass, which is defined as a linear combination of the neutrino

Combining hybrid and opaque scintillator techniques in the search for double beta plus decays
European Physical Journal C: Particles and FieldsDouble beta plus decay is a rare nuclear disintegration process. Difficulties in its measurement arise from suppressed decay probabilities, experimentally challenging decay signatures and low natural abundances of suitable candidate nuclei.

Double Beta Decay Experiments With Loaded Liquid Scintillator
Frontiers in Physics, 2019 Liquid scintillator detectors have many properties which are highly advantageous for neutrino research at the MeV energy scale. There are various choices of additives to an organic liquid scintillator which typically function as the nuclear targets in a ...

Phase Space Factors for Double-Beta Decays
Frontiers in Physics, 2019 Double-beta decay is presently a very studied process both theoretically and experimentally due to its potential to provide valuable information about important, but still unknown issues related to the neutrino properties and conservation of some ...

Study of the double Gamow-Teller transitions using the shell model approach
EPJ Web of Conferences, 2018 The double Gamow-Teller strength distributions in the lightest double beta-decay candidate 48Ca and its isotope 46Ca were calculated using the nuclear shell model by applying the single Gamow-Teller operator two times sequentially on the ground state of ...

Physics Letters B, 2020 Two-neutrino double-beta-decay matrix elements M2ν and single beta-decay branching ratios were calculated for 48Ca and 96Zr in the interacting nuclear shell model using large single-particle valence spaces with well-tested two-body Hamiltonians. For 48Ca

$${{\rho }}$$ ρ exchange contribution to neutrinoless double beta decay
European Physical Journal C: Particles and Fields, 2023 We consider $$\rho $$ ρ meson contributions to neutrinoless double beta decay amplitude stemming from the hadronization of the short distance quark-electron currents. These contributions are evaluated within vacuum dominance approximation.
