Neutron electric dipole moment from lattice QCD [PDF]

, 2005
We carry out a feasibility study for the lattice QCD calculation of the neutron electric dipole moment (NEDM) in the presence of the $\theta$ term. We develop the strategy to obtain the nucleon EDM from the CP-odd electromagnetic form factor $F_3$ at ...

Proton-neutron pairing correlations in the self-conjugate nucleus 42Sc

Physics Letters B, 2021
Collinear laser spectroscopy of the N=Z=21 self-conjugate nucleus 42Sc has been performed at the JYFL IGISOL IV facility in order to determine the change in nuclear mean-square charge radius between the Iπ=0+ ground state and the Iπ=7+ isomer via the ...

Quark Chromoelectric Dipole Moment Contribution to the Neutron Electric Dipole Moment [PDF]

Proceedings of 34th annual International Symposium on Lattice Field Theory — PoS(LATTICE2016), 2017
The quark chromo-electric dipole moment operator and the pseudo-scalar fermion bilinear with which it mixes under renormalization can both be included in a calculation of the electromagnetic form factor of the nucleon using the Schwinger source method.

The design of the n2EDM experiment

European Physical Journal C: Particles and Fields, 2021
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 of carrying out a high-precision search for an electric dipole moment of the ...

Constraining interactions mediated by axion-like particles with ultracold neutrons

Physics Letters B, 2015
We report a new limit on a possible short range spin-dependent interaction from the precise measurement of the ratio of Larmor precession frequencies of stored ultracold neutrons and Hg199 atoms confined in the same volume.

Nucleon electric dipole moment from polarized deep inelastic scattering

Physics Letters B, 2021
In a previous paper [1], we have pointed out the connection between the CP-odd three-gluon (Weinberg) operator and certain twist-four corrections in polarized deep inelastic scattering.
