The history of the search for electric dipole moment (EDM)takes us back in time for more than five decades. EDMs have gained...
The Jülich Electric Dipole moment Investigation (JEDI) Collaboration works on a measurement of the electric dipole moment (EDM) of charged hadrons using a storage ring. Such a dipole moment would violate CP symmetry, providing a test for physics beyond the Standard Model. The JEDI experiment requires a small beam orbit RMS in order to control systematic uncertainties.
Therefore an ongoing...
The direct measurement of the proton or deuteron Electric Dipole Moment (EDM) has never been performed before. These experiments can be done at electrostatic storage ring. As a starting point the magnetic storage ring COSY at Forschungszentrum Jülich can be used. It will require implementation of the electrostatic or electromagnetic beam-bending elements. For testing the electrodes material,...
Precision measurements of the β-energy spectrum in nuclear and neutron decays have a great potential to find possible signatures of new physics beyond the standard electroweak model. Such signatures would produce a distortion of the β-energy spectrum relative to the Standard Model prediction. In Gamow-Teller transitions, these distortions would indicate the presence of the exotic tensor type...
In precision searches for electric dipole moments of charged particles using storage rings, one needs to quantify background signals that stem from false rotations of the magnetic dipole moments in the horizontal magnetic fields of the storage ring. Mapping the spin tune response of a machine with artifically applied longitudinal magnetic fields allows one to probe the magnetic imperfection...
We are developing experiments to study parity nonconservation effects in neutral francium atoms at the ISAC radioactive beam facility at TRIUMF. We are using laser cooling and trapping techniques to prepare the atoms for our measurements and our current effort is based on optical spectroscopy of Stark induced 7s-8s atomic transitions aiming at Standard Model test of the strength of the...
The decay of the free neutron into a proton, electron and antineutrino is the simplest example of the nuclear beta decay. The lifetime of this process is measured either by beam or by storage experiments. Currently, their results show a discrepancy of about 7 s which is also known as the "neutron lifetime puzzle". Two major systematic effects in neutron experiments are losses due to...
The JEDI (Jülich Electric Dipole Investigations) Collaboration aims to carry out a long term project for the measurement of the permanent electric dipole moments of charged particles in a storage ring. As a proof-of-concept, the COoler SYnchrotron (COSY) was equipped with a waveguide RF Wien filter designed to operate at some harmonics of the spin precession frequency ranging from 0.1 to 2...
The JEDI (Jülich Electric Dipole moment Investigations) collaboration performs
a set of experiments at the COSY storage ring in Jülich, within the R&D phase to search for the Electric Dipole Moments (EDMs) of charged particles. A measurement of proton and deuteron EDMs is a sensitive probe of yet unknown CP violation. An EDM observation would also be an indication for physics beyond the...
The Jiangmen Underground Neutrino Observatory (JUNO) will be a 20\,kt liquid scintillator neutrino detector located at Kaiping, Jiangmen in South China. With the data aquisition starting in 2021, its main goal is the determination of the neutrino mass hierarchy from a precise measurement of the energy spectrum of anti-electron-neutrinos 53\,km away from the reactor. To precisely measure the...
In the framework of the Standard Model, CPT symmetry demands the same fundamental prop-
erties for matter and antimatter. The precise measurement of the ground state hyperfine structure
of antihydrogen and its comparison to that of hydrogen is a sensitive test of CPT invariance. A
Ramsey type beam spectroscopy method [1] has the potential to improve this precision by a factor
of 10 over the...
Antimatter is believed to be affected by gravity in exactly the same way as ordinary matter for a variety of good reasons [1], however this has never been measured directly. This will be tested by the ALPHA-g project, which uses a new vertical antihydrogen trap based on the previous ALPHA design (Antihydrogen Laser Physics Apparatus, the first experiment to trap antihydrogen in 2010 [2]). As...
