The theory of electric dipole moments: the view from below
Jordy de Vries
Permanent electric dipole moments (EDMs) of nucleons, nuclei, atoms, and molecules are among the most sensitive probes of CP violation beyond the Standard Model and are intimately…
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 the QCD term with paramagnetic molecules
Heleen Mulder, Rob Timmermans, Jordy de Vries
The experimental search for CP violation in paramagnetic atomic and molecular systems has made impressive progress in recent years. This has led to strong upper limits on the elect…
2D transverse laser cooling of a hexapole focused beam of cold BaF molecules
Joost W. F. van Hofslot, Izabella E. Thompson, Anno Touwen +18
A cryogenic buffer gas beam, an electrostatic hexapole lens, and 2D transverse Doppler laser cooling are combined to produce a bright beam of barium monofluoride (Ba…
