The axion is a highly motivated elementary particle that could address two fundamental
questions in physics—the strong charge-parity (CP) problem and the dark matter mystery …

A permanent electric dipole moment (EDM) of a particle or system is a separation of charge
along its angular momentum axis and is a direct signal of T violation and, assuming CPT …

We calculate the electric dipole moment of the nucleon induced by the quantum
chromodynamics θ term. We use the gradient flow to define the topological charge and use …

Based on the notion that the local dark-matter field of axions or axionlike particles (ALPs) in
our Galaxy induces oscillating couplings to the spins of nucleons and nuclei (via the electric …

We show that proton storage ring experiments designed to search for proton electric dipole
moments can also be used to look for the nearly dc spin precession induced by dark energy …

A concise demonstrative summary of the Symmetric-Hybrid ring design for the storage ring
proton electric dipole moment experiment is presented. Critical issues such as lattice design …

Abstract Nuclotron based Ion Collider fAcility (NICA) project is in progress at the Joint
Institute for Nuclear Research and will start experiments with heavy ions. In the context of the …

This Letter reports the successful use of feedback from a spin polarization measurement to
the revolution frequency of a 0.97 GeV/c bunched and polarized deuteron beam in the …

We propose using the storage ring electric dipole moment (EDM) method to search for the
axion dark matter induced EDM oscillation in nucleons. The method uses a combination of B …

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 …
