First Experimental Limit on the Permanent Electric Dipole Moment of the Deuteron

A. Andres, V. Hejny, A. Nass +68

Permanent electric dipole moments (EDMs) provide a sensitive probe of physics beyond the Standard Model and are directly linked to additional sources of CP violation that could exp…

Maintaining a Resonance Condition of an RF Spin Rotator Through a Feedback Loop in a Storage Ring

V. Hejny, A. Andres, J. Pretz +63

This paper presents the successful application of a phase-lock feedback system to maintain the resonance condition of a radio frequency (rf) spin rotator (specifically, an rf Wien…

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…

Determination of target thickness and luminosity from beam energy losses

H. J. Stein, M. Hartmann, I. Keshelashvili +15

The repeated passage of a coasting ion beam of a storage ring through a thin target induces a shift in the revolution frequency due to the energy loss in the target. Since the freq…

Lineshape of the Lambda(1405) Hyperon Measured Through its Sigma0 pion0 Decay

I. Zychor, M. Büscher, M. Hartmann +12

The pp -> p K+ Y0 reaction has been studied for hyperon masses m(Y0)<1540 MeV/c2 at COSY-Juelich by using a 3.65 GeV/c circulating proton beam incident on an internal hydrogen targ…
