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…

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…

Non-conservation of Lepton Numbers in the Neutrino Sector Could Change the Prospects for Core Collapse Supernova Explosions
Anna M. Suliga, Patrick Chi-Kit Cheong, Julien Froustey +5
We show that interactions violating the conservation of lepton numbers in the neutrino sector could significantly alter the standard low entropy picture for the pre-supernova colla…
