A first extraction of the weak magnetism form factor and Fierz interference term from the In Sn Gamow-Teller transition

L. De Keukeleere, D. Rozpedzik, N. Severijns +5

Spectrum shape measurements in nuclear decay can be used to test physics beyond the Standard Model with results being complementary to high-energy collider experiments. In part…

Achieving ultra-low and -uniform residual magnetic fields in a very large magnetically shielded room for fundamental physics experiments

N. J. Ayres, G. Ban, G. Bison +47

High-precision searches for an electric dipole moment of the neutron (nEDM) require stable and uniform magnetic field environments. We present the recent achievements of degaussing…

A large 'Active Magnetic Shield' for a high-precision experiment

C. Abel, N. J. Ayres, G. Ban +48

We present a novel Active Magnetic Shield (AMS), designed and implemented for the n2EDM experiment at the Paul Scherrer Institute. The experiment will perform a high-sensitivity se…

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…

Muonic atom spectroscopy with microgram target material

A. Adamczak, A. Antognini, N. Berger +26

Muonic atom spectroscopy -- the measurement of the x rays emitted during the formation process of a muonic atom -- has a long standing history in probing the shape and size of nucl…
