Abstract

The permanent neutron electric dipole moment (nEDM) is a highly sensitive probe for exploring physics beyond the Standard Model at the low-energy frontier, particularly in the study of charge-parity (CP) violation. With the ultracold neutron (UCN) source at the Paul Scherrer Institut delivering high neutron statistics and a new experimental apparatus, the n2EDM experiment aims to measure the nEDM with a sensitivity an order of magnitude better than the current best limit of 1.8 × 10⁻²⁶ e·cm. The experiment has now entered the commissioning stage and will soon begin data taking. This talk will provide an overview of the experiment, its current status, and recent developments in magnetometry.

Biography

Wenting Chen, graduated with a Master’s degree from Eidgenössische Technische Hochschule Zürich (ETH Zurich), specializing in particle physics. Her doctoral work focuses on the development of a mercury magnetometer and magnetic field analysis for the n2EDM experiment. She has research experience in laser spectroscopy, exotic atom (muonium) studies, as well as experimental design and data analysis.
