Correcting Aberrations of a Transverse-Field Neutron Resonance Spin Echo Instrument
Stephen J. Kuhn, Sam McKay, Fankang Li +5
The neutron resonance spin echo (NRSE) technique has the potential to increase the Fourier time and energy resolution in neutron scattering by using radio-frequency (rf) neutron sp…
Improved neutron lifetime measurement with UCN
F. M. Gonzalez, E. M. Fries, C. Cude-Woods +41
We report an improved measurement of the free neutron lifetime using the UCN apparatus at the Los Alamos Neutron Science Center. We counted a total of approximately $38\…
Neutron State Entanglement with Overlapping Paths
S. J. Kuhn, S. McKay, J. Shen +12
The development of direct probes of entanglement is integral to the rapidly expanding field of complex quantum materials. Here we test the robustness of entangled neutrons as a qua…
Improved limits on Fierz Interference using asymmetry measurements from the UCNA experiment
Xuan Sun, E. Adamek, B. Allgeier +56
The Ultracold Neutron Asymmetry (UCNA) experiment was designed to measure the -decay asymmetry parameter, , for free neutron decay. In the experiment, polarized ultracold n…
Final results for the neutron -asymmetry parameter from the UCNA experiment
B. Plaster, E. Adamek, B. Allgeier +91
The UCNA experiment was designed to measure the neutron -asymmetry parameter using polarized ultracold neutrons (UCN). UCN produced via downscattering in solid deuterium w…
Monte Carlo Simulations of Trapped Ultracold Neutrons in the UCNτ Experiment
Nathan Callahan, Chen-Yu Liu, Francisco Gonzalez +37
In the UCNτ experiment, ultracold neutrons (UCN) are confined by magnetic fields and the Earth's gravitational field. Field-trapping mitigates the problem of UCN loss on material s…
Measurement of the neutron lifetime using a magneto-gravitational trap
Nathan Callahan
Precision measurements of the free neutron lifetime , when combined with measurements of the axial vector form factor, can be used to test unitarity of the CKM matrix. Non-uni…
Search for dark matter decay of the free neutron from the UCNA experiment: n
X. Sun, E. Adamek, B. Allgeier +57
It has been proposed recently that a previously unobserved neutron decay branch to a dark matter particle () could account for the discrepancy in the neutron lifetime observed i…
New result for the neutron -asymmetry parameter from UCNA
M. A. -P. Brown, E. B. Dees, E. Adamek +56
The neutron -decay asymmetry parameter defines the correlation between the spin of the neutron and the momentum of the emitted electron, which determines $λ=\frac{g_{A}}{g…
Measurement of the neutron lifetime using an asymmetric magneto- gravitational trap and in situ detection
R. W. Pattie, N. B. Callahan, C. Cude-Woods +35
The precise value of the mean neutron lifetime, , plays an important role in nuclear and particle physics and cosmology. It is a key input for predicting the ratio of protons…
