Neutron Electric Dipole Moment on the Lattice [PDF]

EPJ Web of Conferences, 2018
For the neutron to have an electric dipole moment (EDM), the theory of nature must have T, or equivalently CP, violation. Neutron EDM is a very good probe of novel CP violation in beyond the standard model physics.

Neutron Electric Dipole Moment from colored scalars⋆ [PDF]

EPJ Web of Conferences, 2014
We present new contributions to the neutron electric dipole moment induced by a color octet, weak doublet scalar, accommodated within a modified Minimal Flavor Violating framework.

Neutron Electric Dipole Moment at Fixed Topology [PDF]

Modern Physics Letters A, 2009
We describe the finite volume effects of CP-odd quantities, such as the neutron electric dipole moment and the anapole moment in the $\theta$-vacuum, under different topological sectors.

Neutron Electric Dipole Moment from quark Chromoelectric Dipole Moment [PDF]

Proceedings of The 33rd International Symposium on Lattice Field Theory — PoS(LATTICE 2015), 2016
The connection between a regularization-independent symmetric momentum substraction (RI-$\tilde{\rm S}$MOM) and the $\overline{\rm MS}$ scheme for the quark chromo EDM operators is discussed.

Search for a Neutron Electric Dipole Moment. [PDF]

J Res Natl Inst Stand Technol, 2005
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 ...

Neutron electric dipole moment from gauge/string duality [PDF]

Physical Review Letters, 2016
We compute the electric dipole moment of nucleons in the large $N_c$ QCD model by Witten, Sakai and Sugimoto with $N_f=2$ degenerate massive flavors. Baryons in the model are instantonic solitons of an effective five-dimensional action describing the ...

Neutron EDM from Electric and Chromoelectric Dipole Moments of Quarks [PDF]

Physical Review D, 2005
Using QCD sum rules, we calculate the electric dipole moment of the neutron d_n induced by all CP violating operators up to dimension five. We find that the chromoelectric dipole moments of quarks \tilde d_i, including that of the strange quark, provide ...

Novel applications of Lattice QCD: Parton Distributions, proton charge radius and neutron electric dipole moment

EPJ Web of Conferences, 2017
We briefly discuss the current status of lattice QCD simulations and review selective results on nucleon observables focusing on recent developments in the lattice QCD evaluation of the nucleon form factors and radii, parton distribution functions and ...

The pulsed neutron beam EDM experiment [PDF]

EPJ Web of Conferences, 2019
We report on the Beam EDM experiment, which aims to employ a pulsed cold neutron beam to search for an electric dipole moment instead of the established use of storable ultracold neutrons.

An Improved Neutron Electric Dipole Moment Experiment

, 2008
A new measurement of the neutron EDM, using Ramsey's method of separated oscillatory fields, is in preparation at the new high intensity source of ultra-cold neutrons (UCN) at the Paul Scherrer Institute, Villigen, Switzerland (PSI).
