Constraints on the Dark Matter Interpretation $n \to χ + e^{+} e^{-}$ of the Neutron Decay Anomaly with the PERKEO II experiment

M. Klopf, E. Jericha, B. Märkisch +3

Discrepancies from in-beam and in-bottle type experiments measuring the neutron lifetime are on the 4 $σ$ standard deviation level. In a recent publication Fornal and Grinstein prop…

Determination of the Weak Axial Vector Coupling from a Measurement of the Beta-Asymmetry Parameter A in Neutron Beta Decay

D. Mund, B. Maerkisch, M. Deissenroth +5

We report on a new measurement of the neutron beta-asymmetry parameter $A$ with the instrument \perkeo. Main advancements are the high neutron polarization of $P = 99.7 (1)$ from a…

Is the Unitarity of the quark-mixing-CKM-matrix violated in neutron $β$ -decay?

H. Abele, M. Astruc Hoffmann, S. Baessler +6

We report on a new measurement of neutron $β$ -decay asymmetry. From the result \linebreak $A_{0}$ = -0.1189(7), we derive the ratio of the axial vector to the vector coupling constan…
