Neutron Electric Dipole Moment Experiments
The possibility of a non-zero value for neutron EDM continues to be of central importance in physics and cosmology. A non-zero neutron EDM would be a direct evidence for time-reversal symmetry violation. It also implies CP-violation under the assumption of CPT invariance. To date, only two examples of CP-violation have been found: decays of neutral K mesons and B mesons. CP-violation is believe...
متن کاملNeutron Electric Dipole Moment Experiment
A.1.a General Introduction Precision measurements of the properties of the neutron present an opportunity to search for violations of fundamental symmetries and to make critical tests of the validity of the Standard Model (SM) of electroweak (EW) interactions. These experiments have been pursued with great energy and interest since Chadwick [i] discovered the neutron in 1932. Searches for the e...
متن کاملSearch for a Neutron Electric Dipole Moment
The possible existence of a nonzero electric dipole moment (EDM) of the neutron is of great fundamental interest in itself and directly impacts our understanding of the nature of electro-weak and strong interactions. The experimental search for this moment has the potential to reveal new sources of T and CP violation and to challenge calculations that propose extensions to the Standard Model. T...

متن کاملNeutron Electric Dipole Moment at Fixed Topology
We describe the finite volume effects of CP-odd quantities, such as the neutron electric dipole moment and the anapole moment in the θ-vacuum, under different topological sectors. We evaluate the three-point Green’s functions for the electromagnetic current in a fixed non-trivial topological sector in order to extract these CP-odd observables. We discuss the role of zero modes in the CP-odd Gre...
