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…

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…
