Electric dipole moments in natural supersymmetry

Journal of High Energy Physics, 2017
We discuss electric dipole moments (EDMs) in the framework of CP-violating natural supersymmetry (SUSY). Recent experimental results have significantly tightened constraints on the EDMs of electrons and of mercury, and substantial further progress is ...

Scatterers of Non-Electric-Dipole Radiation [PDF]

Nanomaterials
We theoretically demonstrate that nonmagnetic silicon nanodisk dimers, under plane-wave illumination, can achieve electric dipole mode-free by suppressing electric dipole responses at magnetic resonance frequencies through structural parameter tuning ...

Spin tune mapping as a novel tool to probe the spin dynamics in storage rings [PDF]

Physical Review Accelerators and Beams, 2017
Precision experiments, such as the search for electric dipole moments of charged particles using storage rings, demand for an understanding of the spin dynamics with unprecedented accuracy.

Electric Dipole Moment Results from lattice QCD

EPJ Web of Conferences, 2018
We utilize the gradient flow to define and calculate electric dipole moments induced by the strong QCD θ-term and the dimension-6 Weinberg operator. The gradient flow is a promising tool to simplify the renormalization pattern of local operators.

Search for electric dipole moments [PDF]

EPJ 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.

Electric dipole moments from colour-octet scalars

Journal of High Energy Physics, 2022
We present the contributions to electric dipole moments (EDMs) induced by the Yukawa couplings of an additional electroweak doublet of colour-octet scalars.

Interaction potentials, electric moments, polarizabilities, and chemical reactions of YbCu, YbAg, and YbAu molecules

New Journal of Physics, 2021
Ultracold YbAg molecules have been recently proposed as promising candidates for electron electric dipole moment searches Verma et al (2020 Phys. Rev. Lett. 125 153201). Here, we calculate potential energy curves, permanent electric dipole and quadrupole

Electric dipole moment constraints on CP-violating heavy-quark Yukawas at next-to-leading order

Journal of High Energy Physics, 2021
Electric dipole moments are sensitive probes of new phases in the Higgs Yukawa couplings. We calculate the complete two-loop QCD anomalous dimension matrix for the mixing of CP-odd scalar and tensor operators and apply our results for a phenomenological ...

Schiff Screening of Relativistic Nucleon Electric-Dipole Moments by Electrons [PDF]

, 2007
We show, at leading-order in the multipole expansion of the electron-nucleus interaction, that nucleon electric-dipole moments are completely shielded by electrons so that they contribute nothing to atomic electric-dipole moments, even when relativity in
