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 ...

Electric dipole moments: A global analysis
Physical Review C, 2015 We perform a global analysis of searches for the permanent electric dipole moments (EDMs) of the neutron, neutral atoms, and molecules in terms of six leptonic, semileptonic, and nonleptonic interactions involving photons, electrons, pions, and nucleons.

Neutron electric dipole moment from electric and chromoelectric dipole moments of quarks [PDF]
Physical Review D, 2001 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 significant contributions comparable in magnitude to those induced by the quark electric dipole ...

Bound states of a fermion-dyon system
European Physical Journal C: Particles and FieldsThe bound states of fermions in the external field of an Abelian dyon are studied here both analytically and numerically. Their existence is due to the dyon’s electric charge resulting from a polarization of the fermionic vacuum. The configuration of the

Model for the Electric Dipole Moment of the Neutron [PDF]
Physical Review, 1967 A model of the electric dipole moment of the neutron is proposed and evaluated with the help of current algebra and the hypothesis of partially conserved axial-vector current.

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides
Advanced Functional Materials, EarlyView.We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

The Electric Dipole Moment of the Muon
Zeitschrift für Physik C Particles and Fields, 1992 The forthcoming experiment [1] on the anomalous magnetic moment of the muon will be able to search also for an electric dipole moment d μ of the muon with increased sensitivity. A brief survey is given on what various models of CP violation predict for d μ .

Advanced Functional Materials, EarlyView.Here, we provide the reader with the current state of the art in the fabrication of high‐T2‐coherence diamond, optimized through the use of double electron–electron resonance (DEER) spectroscopy. We reveal the main as well as yet unidentified spin defects, the reduction of which is essential for reducing the spin bath and fabricating materials for ...
