There is a deep connection between cosmology—the science of the infinitely large—and
particle physics—the science of the infinitely small. This connection is particularly manifest in …

The search for an electric dipole moment (EDM) of the neutron is a crucial test for theoretical
particle physics models with violation of time and spatial invariance. A new experiment …

Abstract We describe the Fundamental Neutron Physics Beamline (FnPB) facility located at
the Spallation Neutron Source at Oak Ridge National Laboratory. The FnPB was designed …

We analyze the accumulation of ultracold neutrons (UCNs) in a superfluid-helium converter
vessel surrounded by a magnetic multipole reflector. We solved the spin-dependent rate …

We compare the expected effects of so-called gravitationally enhanced depolarization of
ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a …

An analysis is given of the chromoelectric dipole moment of quarks and of the neutron in an
MSSM extension where the matter sector contains an extra vectorlike generation of quarks …

We calculate the effect of a heat current on transporting He 3 dissolved in superfluid He 4 at
ultralow concentration, as will be utilized in a proposed experimental search for the electric …

A passive magnetic shield was designed and constructed for magnetometer tests for the
future neutron electric dipole moment experiment at TRIUMF. The axial shielding factor of …

We present results from a first demonstration of a magnetic field monitoring system for a
neutron electric dipole moment experiment. The system is designed to reconstruct the vector …

The experimental limit on the neutron electric dipole moment is used as a possible probe of
new physics beyond the standard model. Within the minimal supersymmetric standard …
