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 کاملNeutron electric dipole moment on the lattice
We carry out a feasibility study toward a lattice QCD calculation of the neutron electric dipole moment (NEDM) in the presence of the θ term using two different approaches. In the first method, we calculate the CP-odd electromagnetic form factor F3, which becomes the NEDM in the zero momentum transfer limit. At the first order in θ , we derive a formula connecting the lattice three-point functi...
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...
