First Search for Axion-Like Particles in a Storage Ring Using a Polarized Deuteron Beam
Swathi Karanth, Edward J. Stephenson, Seung Pyo Chang +60
Based on the notion that the local dark-matter field of axions or axion-like particles (ALPs) in our Galaxy induces oscillating couplings to the spins of nucleons and nuclei (via t…
First detection of collective oscillations of a stored deuteron beam with an amplitude close to the quantum limit
J. Slim, N. N. Nikolaev, F. Rathmann +41
We investigated coherent betatron oscillations of a deuteron beam in the storage ring COSY, excited by a detuned radio-frequency Wien filter. The beam oscillations were detected by…
A New Beam Polarimeter at COSY to Search for Electric Dipole Moments of Charged Particles
F. Müller, O. Javakhishvili, D. Shergelashvili +53
A calorimetric polarimeter based on inorganic LYSO scintillators is described. It has been designed for use in a storage ring to search for electric dipole moments (EDM) of charged…
Beam-based alignment at the Cooler Synchrotron COSY as a prerequisite for an electric dipole moment measurement
T. Wagner, A. Nass, J. Pretz +47
The Jülich Electric Dipole moment Investigation (JEDI) collaboration aims at a direct measurement of the Electric Dipole Moment (EDM) of protons and deuterons using a storage ring.…
Storage Ring to Search for Electric Dipole Moments of Charged Particles -- Feasibility Study
F. Abusaif, A. Aggarwal, A. Aksentev +98
The proposed method exploits charged particles confined as a storage ring beam (proton, deuteron, possibly He) to search for an intrinsic electric dipole moment (EDM) aligned a…
Extraction of Azimuthal Asymmetries using Optimal Observables
Jörg Pretz, Fabian Müller
Azimuthal asymmetries play an important role in scattering processes with polarized particles. This paper introduces a new procedure using event weighting to extract these asymmetr…
Phase locking the spin precession in a storage ring
N. Hempelmann, V. Hejny, J. Pretz +66
This letter reports the successful use of feedback from a spin polarization measurement to the revolution frequency of a 0.97 GeV/ bunched and polarized deuteron beam in the Coo…
Photoproduction ofeta-pi pairs off nucleons and deuterons
A. Kaeser, F. Mueller, J. Ahrens +66
Quasi-free photoproduction of -pairs has been investigated from threshold up to incident photon energies of 1.4 GeV, respectively up to photon-nucleon invariant masses up to 1.…
