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…

Solid deuterium surface degradation at ultracold neutron sources

A. Anghel, T. L. Bailey, G. Bison +27

Solid deuterium (sD_2) is used as an efficient converter to produce ultracold neutrons (UCN). It is known that the sD_2 must be sufficiently cold, of high purity and mostly in its…

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…
