The current status of electric dipole moments of diamagnetic atoms which involves the synergy between atomic experiments and three different theoretical areas -particle, nuclear and atomic is reviewed. Various models of particle physics that predict CP violation, which is necessary for the existence of such electric dipole moments, are presented. These include the standard model of particle physics and various extensions of it. Effective hadron level combined charge conjugation (C) and parity (P) symmetry violating interactions are derived taking into consideration different ways in which a nucleon interacts with other nucleons as well as with electrons. Nuclear structure calculations of the CP-odd nuclear Schiff moment are discussed using the shell model and other theoretical approaches. Results of the calculations of atomic electric dipole moments due to the interaction of the nuclear Schiff moment with the electrons and the P and time-reversal (T) symmetry violating tensor-pseudotensor electron-nucleus are elucidated using different relativistic many-body theories. The principles of the measurement of the electric dipole moments of diamagnetic atoms are outlined. Upper limits for the nuclear Schiff moment and tensor-pseudotensor coupling constant are obtained combining the results of atomic experiments and relativistic many-body theories. The coefficients for the different sources of CP violation have been estimated at the elementary particle level for all the diamagnetic atoms of current experimental interest and their implications for physics beyond the standard model is discussed. Possible improvements of the current results of the measurements as well as quantum chromodynamics, nuclear and atomic calculations are suggested. .+y Nuclear tests of fundamental interactions and symmetries -31.15.ve Electron correlation calculations for atoms and ions: ground state PACS Higgs doublet modelsThe Higgs boson was recently discovered [4,5], but the detailed Higgs potential is still unknown. There are currently many well-motivated extensions of the Higgs sector BSM. The most well-known one is the two-Higgs doublet model (2HDM), and extensive studies have been performed [79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97].As the Higgs boson has a small coupling with light fermions, the one-loop level fermion EDM and the CP-odd four-fermion interactions are suppressed in 2HDM [98,99]. The leading contribution to the elementary level CP violation contributing to the EDM is the two-loop level Barr-Zee type diagram [79] [ Fig. 4 (b)], enhanced by the large Yukawa coupling of the top quark of the inner loop. The Barr-Zee type diagram contribution to the EDM of SM fermion can be written as [79]

“…It therefore seems very likely that the best limits for both C T and S could be obtained by combining our calculated values presented in this work and the results of the new generation of experiments for 129 Xe when they come to fruition. This limit for S in conjunction with the recent nuclear structure calculations [29] and quantum chromodynamics (QCD), would yield new limits for θ QCD and CP violating coupling constants involving chromo EDMs of quarks.…”

The parity (P) and time-reversal (T) odd coupling constant associated with the tensorpseudotensor (T-PT) electron-nucleus interaction and the nuclear Schiff moment (NSM) have been determined by combining the result of the measurement of the electric dipole moment (EDM) of 129 Xe atom and calculations based on the relativistic coupled-cluster (RCC) theory. Calculations using various relativistic many-body methods have been performed at different levels of approximation and their accuracies are estimated by comparing the results of the calculated dipole polarizability of the ground state of the above atom with its most precise available experimental data. The nonlinear terms that arise in the RCC theory at the singles and doubles approximation were found to be crucial for achieving high accuracy in the calculations. Our results for the 129 Xe EDM due to the odd T-PT interaction and the NSM are, respectively, dA = 0.501 × 10 −20 CT σN |e|cm and dA = 0.336 × 10 −17 S |e| f m 3 |e|cm. These results in combination with the future EDM measurements in atomic Xe could provide the most accurate limits for the T-PT coupling constant and NSM. PACS numbers:The search for the electric dipole moment (EDM) is now in its seventh decade [1,2]. The observation of an EDM of an elementary particle or a composite system would be an unambiguous signature of the violations of parity (P) and time-reversal (T) symmetries. T violation implies charge conjugation-parity (CP) violation via the CPT theorem [3]. The standard model (SM) of elementary particle physics provides explanations of the experimentally observed hadronic CP violation in the decays of neutral K [4] and B [5][6][7] mesons, but the amount of CP violation predicted by the SM is not sufficient to account for the matter-antimatter asymmetry in the Universe [8]. The current limits for CP violating coupling constants deduced from the atomic EDMs are several orders of magnitude higher than the predictions of these quantities by the SM [9][10][11]. In addition, atomic EDMs can probe CP violation originating from leptonic, semileptonic and hadronic CP sources. Combining atomic EDM measurements with high precision many-body calculations, it is possible to obtain various CP violating coupling constants at the levels of the nucleus and the electron. Newly proposed EDM experiments on diamagnetic and paramagnetic atoms hold the promise of improving the sensitivity of the current measurements by at least a few orders of magnitude [12][13][14][15][16]. The EDMs of diamagnetic atoms arise predominantly from the electron-nucleus tensor-pseudotensor (T-PT) interaction and interaction of electrons with the nuclear Schiff moment (NSM) [17]. The electron-nucleus T-PT interaction is due to the CP violating electron-nucleon interactions which translates to CP violating electron-quark interactions at the level of elementary particles. The NSM on the other hand could exist due to CP violat- * bijaya@prl.res.in ing nucleon-nucleon interactions and the EDM of nucleons and both of them in turn could o...

Nuclear EDMs are calculated using wave functions obtained by the pair-truncated shell model (PTSM) [8]. The upper limit of the nuclear EDM is estimated only for the 129 Xe ground state (spin and parity 1/2 + ) since in other Xe nuclei the ground states have spin and parity 3/2 + .…”

Abstract. It is evidence for an extension of the Standard Model in particle physics, if static electric dipole moments (EDMs) are measured for any elementary particle. The nuclear EDM arises mainly from two sources: one comes from asymmetric charge distribution in a nucleus and the other is due to the nucleon intrinsic EDM. We estimate the nuclear EDMs from two sources for the 1/2 + 1 states in Xe isotopes by a shell model approach using full orbitals between magic numbers 50 and 82.
