EDM: Neutron electric dipole moment measurement [PDF]

Journal of large-scale research facilities JLSRF, 2016
An electric dipole moment (EDM) of the neutron would be a clear sign of new physics beyond the standard model of particle physics. The search for this phenomenon is considered one of the most important experiments in fundamental physics and could provide key information on the excess of matter versus antimatter in the universe.

Uncovering the Lipid Interface in Neurotransmission: Single Molecule Measurements of Neurotransmitters Interacting with Membranes Reveal Species Dependent Membrane Binding

Advanced Science, EarlyView.
Using single‐molecule whispering gallery mode sensors, neurotransmitter‐specific membrane binding signatures are measured that reveal intrinsically distinct interaction kinetics and orientations on a lipid membrane. Abstract Neurotransmitters (NTs) have traditionally been understood to act via aqueous‐phase receptor binding, but growing evidence ...

Optimization of the Magnetic Environment Inside a Magnetically Shielded Enclosure for the Measurement of the Neutron Electric Dipole Moment [PDF]

EPJ Web of Conferences
The search of the Electric Dipole Moment of the neutron (nEDM) is the current goal of several experiments around the world. One key element for these experiments is a very stringent control of the magnetic field environment in which the nEDM is measured.

Nucleon matrix element of Weinberg's CP-odd gluon operator from the instanton vacuum

Physics Letters B, 2021
We calculate the nucleon matrix element of Weinberg's dimension-6 CP-odd gluon operator fabc(F˜μν)a(Fμρ)b(Fρν)c in the instanton vacuum. In leading order of the instanton packing fraction, the dimension-6 operator is effectively proportional to the ...

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

Advanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Dynamical CP Violation and Flavour-Changing Processes [PDF]

, 2001
We investigate the phenomenological constraints on a model where, besides the standard model Higgs sector, there is an effective new strong interaction acting on the third generation of quarks and characterized by a $\theta$-like term. This $\theta$ term

Measurement of the permanent electric dipole moment of the neutron [PDF]

, 2020
We present the result of an experiment to measure the electric dipole moment EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magnetic fields with ultracold neutrons (UCN).

THE ELECTRIC AND MAGNETIC DIPOLE MOMENTS OF THE NEUTRON* [PDF]

Transactions of the New York Academy of Sciences, 1977
In 1950 Purcell and Ramsey pointed out that the parity arguments then used to prove that particles and nuclei could not have electric dipole moments, must be based on an experimental rather than a theoretical basis.

Wide Band Gap Boron Nitride Nanodots‐Incorporated Polyetherimide Dielectrics for High‐Temperature Dielectric Energy Storage

Advanced Science, EarlyView.
The inherent conjugation effects between molecular chains in PEI dielectrics induce substantial energy loss escalation at elevated temperatures. This study incorporated BNNDs into PEI films, successfully achieving effective capture of motion charges under high‐temperature conditions.

A strange contribution to the neutron EDM

Journal of High Energy Physics
We analyze the contribution of hypothetical quark electric dipoles to the electric dipole moment (EDM) of the neutron. Particular emphasis is devoted to the strange quark contribution.
