Positron-Emitting and Electron-Capturing Double-Beta Processes in the Standard Model and Beyond
Lukáš Gráf, Jenni Kotila, Oliver Scholer
We study positron-emitting and electron-capturing double-beta-decay modes as probes complementary to the usual double beta decay. Motivated by the proposed NuDoubt++ experiment, we…
Neutrino helicity oscillations in astrophysical environments: a many-body approach
Yiheng Xu, Julien Froustey, George M. Fuller +2
Neutrino rest mass enables left-handed states to "flip" to right-handed states and vice versa. In-medium effects can enhance the probability for such spin-flip. We demonstrate that…
Search for Sterile Neutrinos with CUPID-0
O. Azzolini, J. W. Beeman, F. Bellini +50
Sterile neutrinos are well-motivated extensions of the Standard Model, introduced to address fundamental questions such as the origin of neutrino masses and the nature of dark matt…
Less structure on Mpc scales from decaying sterile neutrino dark matter
MarÃa Dias Astros, Lukáš Gráf, Stefan Vogl
Late decays of dark matter to a lighter, warm dark matter component are a known way to reduce the amplitude of the matter power spectrum on scales of Mpc. However, only very fe…
Importance of Loop Effects in Probing Lepton Number Violation
Lukáš Gráf, Chandan Hati, Ana MartÃn-Galán +1
The discovery of the lepton number violation would be a smoking gun signal for physics beyond the Standard Model, and its most sensitive probe is the search for neutrinoless double…
