Measurement of the neutron incoherent scattering length of Hg using stored ultracold neutrons

C. Abel, K. Bodek, E. Chanel +35

We present the first direct measurement of the neutron incoherent scattering length of Hg. The measurement was performed with the Ramsey apparatus of the neutron electric…

Search for an interaction mediated by axion-like particles with ultracold neutrons at the PSI

N. J. Ayres, G. Bison, K. Bodek +44

We report on a search for a new, short-range, spin-dependent interaction using a modified version of the experimental apparatus used to measure the permanent neutron electric dipol…

Search for ultralight axion dark matter in a side-band analysis of a 199Hg free-spin precession signal

C. Abel, N. J. Ayres, G. Ban +35

Ultra-low-mass axions are a viable dark matter candidate and may form a coherently oscillating classical field. Nuclear spins in experiments on Earth might couple to this oscillati…

Oscillations: Sensitivity of a first UCN beam experiment

G. Ban, J. Chen, P. -J. Chiu +11

Oscillations of the neutron into a hidden sector particle are processes predicted in various Standard Model extensions. This extra channel for neutron disappearance has not been te…

Johnson-Nyquist Noise Effects in Neutron Electric-Dipole-Moment Experiments

N. J. Ayres, G. Ban, G. Bison +37

Magnetic Johnson-Nyquist noise (JNN) originating from metal electrodes, used to create a static electric field in neutron electric-dipole-moment (nEDM) experiments, may limit the s…

Probing neutron-hidden neutron transitions with the MURMUR experiment

C. Stasser, G. Terwagne, J. Lamblin +6

MURMUR is a new passing-through-walls neutron experiment designed to constrain neutron/hidden neutron transitions allowed in the context of braneworld scenarios or mirror matter mo…
