Measurement of the permanent electric dipole moment of the neutron

C. Abel, S. Afach, N. J. Ayres +81

We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magn…

Sterile Neutrino Constraints from the STEREO Experiment with 66 days of Reactor-on Data

H. Almazán, P. del Amo Sanchez, L. Bernard +25

The reactor antineutrino anomaly might be explained by the oscillation of reactor antineutrinos toward a sterile neutrino of eV mass. In order to explore this hypothesis, the STERE…
