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.

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.

750 GeV diphoton resonance and electric dipole moments
Physics Letters B, 2016 We examine the implication of the recently observed 750 GeV diphoton excess for the electric dipole moments of the neutron and electron. If the excess is due to a spin zero resonance which couples to photons and gluons through the loops of massive vector-

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 ...

The neutron electric dipole form factor in the perturbative chiral quark model
, 2006 We calculate the electric dipole form factor of the neutron in a perturbative chiral quark model, parameterizing CP-violation of generic origin by means of effective electric dipole moments of the constituent quarks and their CP-violating couplings to ...
