Measurement of the Free Neutron Lifetime in a Magneto-Gravitational Trap with In Situ Detection
R. Musedinovic, L. S. Blokland, C. B. Cude-Woods +32
Here we publish three years of data for the UCNtau experiment performed at the Los Alamos Ultra Cold Neutron Facility at the Los Alamos Neutron Science Center. These data are in ad…
An experimental search for an explanation of the difference between beam and bottle neutron lifetime measurements
M. F. Blatnik, L. S. Blokland, N. Callahan +32
The past two decades have yielded several new measurements and reanalysis of older measurements of the neutron lifetime. These have led to a 4.4 standard deviation discrepancy betw…
Characterization of electroless nickel-phosphorus plating for ultracold-neutron storage
H. Akatsuka, T. Andalib, B. Bell +51
Electroless nickel plating is an established industrial process that provides a robust and relatively low-cost coating suitable for transporting and storing ultracold neutrons (UCN…
Fill and dump measurement of the neutron lifetime using an asymmetric magneto-gravitational trap
C. Cude-Woods, F. M. Gonzalez, E. M. Fries +39
The past two decades have yielded several new measurements and reanalyses of older measurements of the neutron lifetime. These have led to a 4.4 standard deviation discrepancy betw…
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\…
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…
Using Nab to determine correlations in unpolarized neutron decay
L. J. Broussard, S. Baeßler, T. L. Bailey +28
The Nab experiment will measure the ratio of the weak axial-vector and vector coupling constants with precision and search for a Fierz term $b_…
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…
Search for the Neutron Decay n X+ where X is a dark matter particle
Z. Tang, M. Blatnik, L. J. Broussard +21
In a recent paper submitted to Physical Review Letters, Fornal and Grinstein have suggested that the discrepancy between two different methods of neutron lifetime measurements, the…
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…
