11. Progress Towards a Precision Measurement of the Neutron Lifetime Using Magnetically Trapped Ultracold Neutrons
Published: 1/1/2006
Authors: P.-N. Seo, Kevin J Coakley, J M Doyle, F H DuBose, R Golub, E Korobkina, S K Lamoreaux, Hans P Mumm, C M O'Shaughnessy, G R Palmquis, A K Thompson, Grace L Yang, L Yang, Paul R Huffman
Abstract: As part of an on-going program utilizing magnetically trapped ultracold neutrons (UCNs,) we are developing a technique that offers the possibility of improving the precision of the neutron lifetime by more than an order of magnitude. The experiment w ...

12. Radiative Beta Decay of the Free Neutron
Published: 2/2/2009
Authors: R L Cooper, T E. Chupp, Maynard S Dewey, Thomas R Gentile, Hans P Mumm, Jeffrey S Nico, Alan K Thompson, B M Fisher, I Kremsky, F E. Wietfeldt, E J Beise, H Breuer, K G Kiriluk, J Bryne, Kevin J Coakley, Changbo Fu
Abstract: The theory of quantum electrodynamics predicts that the beta decay of the neutron into a proton, electron, and antineutrino is accompanied by a continuous spectrum of emitted photons described as inner bremsstrahlung. While this phenomenon has been ...

14. Search for a T-odd, P-even Triple Correlation in Neutron Decay
Published: 9/14/2012
Authors: Jeffrey S Nico, T E. Chupp, K P Coulter, R L Cooper, S. J. Freeman, B. K. Fujikawa, A. Garcia, G L. Jones, Hans P Mumm, Alan K Thompson, C A Trull, F. E Wiefeldt, J. F. Wilkerson
Abstract: Time-reversal-invariance (T) violation, or equivalently, assuming charge-conjugation-parity-time-reversal (CPT) invariance, CP violation may explain the observed cosmological baryon asymmetry as well as signal physics beyond the Standard Model. In th ...
