CP Violation in Decays: Standard Model Benchmarks and Isospin-Breaking New Physics
Robert Fleischer, Jelle Groot, K. Keri Vos
The penguin loop-suppressed decays are highly sensitive to contributions of hypothetical heavy new particles. Particularly interesting probes for testing the Standard Mod…

Big Bang Nucleosynthesis and the Neutrino-Extended Standard Model Effective Field Theory
Pieter Braat, Jordy de Vries, Jelle Groot +2
We study the impact of light GeV-scale heavy neutral leptons (HNLs) on Big Bang nucleosynthesis (BBN) in the neutrino-extended Standard Model Effective Field Theory (SMEFT). We…

Probing light sterile neutrinos in left-right symmetric models with displaced vertices and neutrinoless double beta decay
Jordy de Vries, Herbi K. Dreiner, Jelle Groot +2
An investigation of relatively light (GeV-scale), long-lived right-handed neutrinos is performed within minimal left-right symmetric models using the neutrino-extended Standard Mod…
