Scalarful double beta decay
Jordy de Vries, Lukáš Gráf, Vaisakh Plakkot +1
We revisit scalar emissions in double beta decays of nuclei, often discussed in the context of Majoron models, in light of the latest developments on the study of neutrinoless doub…
ECFA Higgs, electroweak, and top Factory Study
H. Abidi, J. A. Aguilar-Saavedra, S. Airen +373
The ECFA Higgs, electroweak, and top Factory Study ran between 2021 and 2025 as a broad effort across the experimental and theoretical particle physics communities, bringing togeth…
Neutrinoless double beta decay rates and the scenario
Vaisakh Plakkot
The possible Majorana nature of neutrinos leads to lepton-number-violating effects such as neutrinoless double beta decay. The standard study of this process involves mass-dependen…
Confronting the low-scale seesaw and leptogenesis with neutrinoless double beta decay
J. de Vries, M. Drewes, Y. Georis +2
We revisit the impact of heavy neutrinos with masses in the MeV-GeV range on neutrinoless double beta decay () in view of updated results for the lifetime of this process.…
Catalogues of Cosmologically Self-Consistent Hadronic QCD Axion Models
Luca Di Luzio, Sebastian Hoof, Coenraad Marinissen +1
We extend the catalogue of "phenomenologically preferred" hadronic axion models to include heavy fermion representations associated with higher-dimensional decay operators. The lat…
Neutrinoless double beta decay rates in the presence of light sterile neutrinos
W. Dekens, J. de Vries, D. Castillo +5
We investigate neutrinoless double-beta decay () in minimal extensions of the Standard Model of particle physics where gauge-singlet right-handed neutrinos give rise to Di…
