First measurement of the antihydrogen production cross section through the charge-exchange reaction of low-energy antiprotons with orthopositronium
GBAR Collaboration, P. Adrich, I. Belosevic +42
The GBAR experiment has measured the formation rate of antihydrogen from antiproton impact on a positronium cloud for antiproton kinetic energies of 4 and 6 keV. This is the first…
A determination of the backscattering probability of low-energy antiprotons
GBAR Collaboration, K. Park, E. Perez +42
It is commonly assumed that antiprotons impinging on a material surface annihilate promptly with the nuclei of the material. However, at kinetic energies of a few keV, this assumpt…
Record accumulation of antiprotons in a Penning-Malmberg Trap and their preparation for improved production of antihydrogen beams
B. Lee, B. Kim, P. Adrich +35
CERN's AD/ELENA ``antimatter factory'' - unique worldwide - serves several experiments, all of which use electromagnetic traps to accumulate antiprotons for fundamental science. Th…
Production of antihydrogen atoms by 6 keV antiprotons through a positronium cloud
P. Adrich, P. Blumer, G. Caratsch +61
We report on the first production of an antihydrogen beam by charge exchange of 6.1 keV antiprotons with a cloud of positronium in the GBAR experiment at CERN. The antiproton beam…
Manipulation of gravitational quantum states of a bouncing neutron with the GRANIT spectrometer
Benoit Clément, Stefan Baeßler, Valery V. Nesvizhevsky +9
The bouncing neutron is one of the rare system where gravity can be studied in a quantum framework. To this end it is crucial to be able to select some specific gravitational quant…
Search for passing-through-walls neutrons constrains hidden braneworlds
Michael Sarrazin, Guillaume Pignol, Jacob Lamblin +6
In many theoretical frameworks our visible world is a -brane, embedded in a multidimensional bulk, possibly coexisting with hidden braneworlds. Some works have also shown that m…
Measurement of the neutron electric dipole moment via spin rotation in a non-centrosymmetric crystal
V. V. Fedorov, M. Jentschel, I. A. Kuznetsov +8
We have measured the neutron electric dipole moment using spin rotation in a non-centrosymmetric crystal. Our result is d_n = (2.5 +- 6.5(stat) +- 5.5(syst)) 10^{-24} e cm. The dom…
Test experiment to search for a neutron EDM by the Laue diffraction method
V. V. Fedorov, E. G. Lapin, E. Lelievre-Berna +6
A prototype experiment to measure the neutron electric dipole moment (nEDM) by spin-rotation in a non-centrosymmetric crystal in Laue geometry was carried out in order to investiga…
Is the Unitarity of the quark-mixing-CKM-matrix violated in neutron -decay?
H. Abele, M. Astruc Hoffmann, S. Baessler +6
We report on a new measurement of neutron -decay asymmetry. From the result \linebreak = -0.1189(7), we derive the ratio of the axial vector to the vector coupling constan…
