Temperature dependent ultracold neutron transmission in D gas a test of the Young-Koppel model

G. Bison, R. Grössle, K. Kirch +4

The Young-Koppel model (YK) describes comprehensively the interaction of slow neutrons with diatomic gases such as H and D. This paper reports on the first experimental res…

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…

In-situ measurement of the velocity spectrum of ultracold neutrons and its evolution using an oscillating detector

D. Rozpedzik, K. Bodek, K. Kirch +5

Ultracold neutrons (UCNs) are used in experiments investigating fundamental interactions, testing the Standard Model of particle physics and searching for phenomena beyond it. Know…

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…

A search for neutron to mirror neutron oscillation using neutron electric dipole moment measurements

Prajwal Mohanmurthy, Albert R. Young, Jeff A. Winger +1

Baryon number violation is a key ingredient of baryogenesis. It has been hypothesized that there could also be a parity-conjugated copy of the standard model particles, called mirr…

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…
