Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

We present the design of a next-generation experiment, n2EDM, currently under
construction at the ultracold neutron source at the Paul Scherrer Institute (PSI) with the aim …

While the international nEDM collaboration at the Paul Scherrer Institut (PSI) took data in
2017 that covered a considerable fraction of the parameter space of claimed potential …

The neutron's lifetime is a critical parameter in the standard model. Its measurements,
particularly measurements using both beamline and ultracold neutron storage techniques …

We report the performance of a magnetically silent optically pumped cesium magnetometer
with a statistical sensitivity of 3.5 pT/\(\sqrt {\textrm {Hz}}\) at 1 Hz and a stability of 90 fT over …

High-precision searches for an electric dipole moment of the neutron (nEDM) require stable
and uniform magnetic field environments. We present the recent achievements of …

We report on a search for a new, short-range, spin-dependent interaction using a modified
version of the experimental apparatus used to measure the permanent neutron electric …

We present a coil system designed to generate a highly uniform magnetic field for the
n2EDM experiment at the Paul Scherrer Institute. It consists of a main $ B_0 $ coil and a set …

We report the performance of a magnetically silent optically pumped cesium magnetometer
with a statistical sensitivity of 3.9 pT and a stability of 90 fT over 150 seconds of …

Violation of the combined symmetry of charge conjugation and parity (CP) is one of the three
essential criteria to explain the baryon asymmetry of the Universe, ie, the long-standing …
