Flavorful Lepton-Number-Violating SMEFT: Loop Mixing, and Rare Meson Decays

Lukáš Gráf, Chandan Hati, Ana Martín-Galán +1

We investigate how one-loop operator mixing reshapes the flavor sensitivity of lepton-number-violating dimension-7 SMEFT interactions. Using both bottom-up and top-down EFT approac…

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 Martín-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…

Neutrinoless Double Beta Decay without Vacuum Majorana Neutrino Mass

Lukáš Gráf, Sudip Jana, Oliver Scholer +1

We present a proof-of-concept extension to the Standard Model that can generate a non-vanishing neutrinoless double beta decay () signal without the existence of Majorana neu…

DoBe -- A Python Tool for Neutrinoless Double Beta Decay

Oliver Scholer, Jordy de Vries, Lukáš Gráf

We present DoBe, a Python tool for the computation of neutrinoless double beta decay () rates in terms of lepton-number-violating operators in the Standard Model Effective…

Unraveling the Decay Mechanisms

Lukáš Gráf, Manfred Lindner, Oliver Scholer

We discuss the possibilities of distinguishing among different mechanisms of neutrinoless double beta decay arising in the effective field theory framework. Following the review an…

Timing the Neutrino Signal of a Galactic Supernova

Rasmus S. L. Hansen, Manfred Lindner, Oliver Scholer

We study several methods for timing the neutrino signal of a Galactic supernova (SN) for different detectors via Monte Carlo simulations. We find that, for the methods we studied,…
