Hadron Electric Dipole Moments from CP-Odd Operators of Dimension Five Via QCD Sum Rules: The Vector Meson [PDF]

, 1999
We present a complete analysis of the electric dipole moment (EDM) of the \rho-meson induced by CP violating operators of dimension 4 and 5 within the QCD sum rules approach.

Higgs-Mediated Electric Dipole Moments in the MSSM: An Application to Baryogenesis and Higgs Searches [PDF]

, 2002
We perform a comprehensive study of the dominant two- and higher-loop contributions to the $^{205}$Tl, neutron and muon electric dipole moments induced by Higgs bosons, third-generation quarks and squarks, charginos and gluinos in the Minimal ...

Electric dipole moments in split supersymmetry [PDF]

Physics Letters B, 2006
We perform a quantitative study of the neutron and electron electric dipole moments (EDM) in Supersymmetry, in the limit of heavy scalars. The leading contributions arise at two loops. We give the complete analytic result, including a new contribution associated with Z-Higgs exchange, which plays an important and often leading role in the neutron EDM ...

The nucleon electric dipole moment with the gradient flow: the $\theta$-term contribution [PDF]

, 2015
We propose a new method to calculate electric dipole moments induced by the strong QCD $\theta$-term. The method is based on the gradient flow for gauge fields and is free from renormalization ambiguities.

Confronting Higgcision with electric dipole moments [PDF]

Journal of High Energy Physics, 2014
Current data on the signal strengths and angular spectrum of the 125.5 GeV Higgs boson still allow a CP-mixed state, namely, the pseudoscalar coupling to the top quark can be as sizable as the scalar coupling: $C_u^S \approx C_u^P =1/2$. CP violation can then arise and manifest in sizable electric dipole moments (EDMs).

The Electric Dipole Moment of the Nucleons in Holographic QCD

, 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.

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 ...

Improved indirect limits on charm and bottom quark EDMs

Journal of High Energy Physics, 2022
We derive indirect limits on the charm and bottom quark electric dipole moments (EDMs) from paramagnetic AMO and neutron EDM experiments. The charm and bottom quark EDMs generate CP-odd photon-gluon operators and light quark EDMs at the c- and b-quark ...

Neutron Electric Dipole Moment from Isovector Quark Chromo-Electric Dipole Moment

Proceedings 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.
