A search for neutron to mirror-neutron oscillations
C. Abel, N. J. Ayres, G. Ban +40
It has been proposed that there could be a mirror copy of the standard model particles, restoring the parity symmetry in the weak interaction on the global level. Oscillations betw…
Statistical sensitivity of the nEDM apparatus at PSI to neutron mirror-neutron oscillations
C. Abel, N. Ayres, G. Bison +33
The neutron and its hypothetical mirror counterpart, a sterile state degenerate in mass, could spontaneously mix in a process much faster than the neutron -decay. Two groups hav…
Characterization of the Global Network of Optical Magnetometers to search for Exotic Physics (GNOME)
S. Afach, D. Budker, G. DeCamp +21
The Global Network of Optical Magnetometers to search for Exotic physics (GNOME) is a network of geographically separated, time-synchronized, optically pumped atomic magnetometers…
Demonstration of sensitivity increase in mercury free-spin-precession magnetometers due to laser-based readout for neutron electric dipole moment searches
G. Ban, G. Bison, K. Bodek +31
We report on a laser based Hg co-magnetometer deployed in an experiment searching for a permanent electric dipole moment of the neutron. We demonstrate a more than five tim…
