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…

Pilot bunch and co-magnetometry of polarized particles stored in a ring

J. Slim, F. Rathmann, A. Andres +60

In polarization experiments at storage rings, one of the challenges is to maintain the spin-resonance condition of a radio-frequency spin rotator with the spin-precessions of the o…

Spin decoherence and off-resonance behavior of radiofrequency-driven spin rotations in storage rings

N. N. Nikolaev, F. Rathmann, J. Slim +60

Radiofrequency-driven resonant spin rotators are routinely used as standard instruments in polarization experiments in particle and nuclear physics. Maintaining the continuous exac…

Near-field coded-mask technique and its potential for proton therapy monitoring

Ronja Hetzel, Vitalii Urbanevych, Andreas Bolke +14

Objective. Prompt-gamma imaging encompasses several approaches for online monitoring of beam range or deposited dose distribution in proton therapy. We test one of the imaging tech…

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…

Search for a dark photon in the decay

COSY Collaboration, P. Adlarson, W. Augustyniak +113

The presently world largest data sample of pi0 --> gamma e+e- decays containing nearly 5E5 events was collected using the WASA detector at COSY. A search for a dark photon U produc…

Measurement of the eta->3pi0 Dalitz Plot Distribution with the WASA Detector at COSY

COSY Collaboration

In the first production run of the WASA experiment at COSY, the eta decay into three neutral pions was measured in proton-proton interactions at a proton beam kinetic energy of 1.4…
