Beam asymmetry measurements on the photoproduction off neutrons
G. Mandaglio, F. Mammoliti, M. Manganaro +30
The beam asymmetry in the photoproduction of negative pions from quasi-free neutrons in a deuterium target was measured at Graal in the energy interval 700 - 1500 MeV and a wid…
Testing isotropy of the universe using the Ramsey resonance technique on ultracold neutron spins
I. Altarev, G. Ban, G. Bison +38
Physics at the Planck scale could be revealed by looking for tiny violations of fundamental symmetries in low energy experiments. In 2008, a sensitive test of the isotropy of the U…
Search for light-speed anisotropies using Compton scattering of high-energy electrons
Dominique Rebreyend
Based on the high sensitivity of Compton scattering off ultra relativistic electrons, the possibility of anisotropies in the speed of light is investigated. The result discussed in…
New constraints on Lorentz invariance violation from the neutron electric dipole moment
I. Altarev, C. A. Baker, G. Ban +40
We propose an original test of Lorentz invariance in the interaction between a particle spin and an electromagnetic field and report on a first measurement using ultracold neutrons…
Limits on light-speed anisotropies from Compton scattering of high-energy electrons
J. -P. Bocquet, D. Moricciani, V. Bellini +35
The possibility of anisotropies in the speed of light relative to the limiting speed of electrons is considered. The absence of sidereal variations in the energy of Compton-edge ph…
A new limit on the light speed isotropy from the GRAAL experiment at the ESRF
V. G. Gurzadyan, V. Bellini, M. Beretta +32
When the electrons stored in the ring of the European Synchrotron Radiation Facility (ESRF, Grenoble) scatter on a laser beam (Compton scattering in flight) the lower energy of the…
