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

open access: yes, 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 Electric Dipole Moment from Isovector Quark Chromo-Electric Dipole Moment

open access: yesProceedings of The 40th International Symposium on Lattice Field Theory — PoS(LATTICE2023)
We present results from our lattice QCD study of the contribution of the isovector quark cEDM (qcEDM) operator to the neutron EDM. The calculation was carried out on four 2+1+1-flavor highly improved staggered quark ensembles (provided to us by the MILC collaboration) using Wilson-clover quarks to construct correlation functions.

An improved search for the electric dipole moment of the τ lepton

open access: yesJournal of High Energy Physics, 2022
We report a measurement of the electric dipole moment of the τ lepton (dτ) using an 833 fb −1 data sample collected near the Υ(4S) resonance, with the Belle detector at the KEKB asymmetric-energy e + e − collider.

Schiff moment of the Mercury nucleus and the proton dipole moment

open access: yes, 2003
We calculated the contribution of internal nucleon electric dipole moments to the Schiff moment of $^{199}$Hg. The contribution of the proton electric dipole moment was obtained via core polarization effects that were treated in the framework of random ...

The Electric Dipole Moment of the Nucleons in Holographic QCD

open access: yes, 2007
We introduce the strong CP-violation in the framework of AdS/QCD model and calculate the electric dipole moments of nucleons as well as the CP-violating pion-nucleon coupling.

Search for electric dipole moments [PDF]

open access: yesEPJ Web of Conferences, 2020
Searches for permanent electric dipole moments of fundamental particles and systems with spin are the experiments most sensitive to new CP violating physics and a top priority of a growing international community. We briefly review the current status of the field emphasizing on the charged leptons and lightest baryons.

Search for electric dipole moments in storage rings

open access: yesEPJ Web of Conferences, 2016
The JEDI collaboration aims at making use of storage ring to provide the most precise measurement of the electric dipole moments of hadrons. The method makes exploits a longitudinal polarized beam. The existence an electric dipole moment would generate a

All-Optical Sensing of the Components of the Internal Local Electric Field in Proteins

open access: yesIEEE Photonics Journal, 2012
Here, we present a new all-optical method of interrogation of the internal electric field vector inside proteins. The method is based on experimental evaluation of the permanent dipole moment change upon excitation and the pure electronic transition ...

Strong CP violation and the neutron electric dipole form factor

open access: yes, 2005
We calculate the neutron electric dipole form factor induced by the CP violating theta-term of QCD, within a perturbative chiral quark model which includes pion and kaon clouds.

Neutron electric dipole moment in lattice QCD [PDF]

open access: yesPhysical Review Letters, 1989
We present an exploratory computation of the electric dipole moment of the neutron induced by a {ital CP}-violating {theta} term in the QCD Lagrangian in the framework of quenched lattice QCD. We find {ital d}{sub {ital N}}{approx}{minus}4{times}10{sup {minus}14}{theta}e cm.
