Reanalysis of the $\beta -\overline{{\nu }_e}$ Angular Correlation Measurement from the aSPECT Experiment with New Constraints on Fierz Interference

M. Beck, W. Heil, C. Schmidt +4

On the basis of revisions of some of the systematic errors, we reanalyzed the electron-antineutrino angular correlation ($a$ coefficient) in free neutron decay inferred from the re…
