$A_{\beta }[E_{\beta }]$ in ${}^{37}$K decay: new physics with opposite $\beta$ helicity

Melissa Anholm, J. A. Behr, D. G. Melconian +5

By extending our analysis and simulations of our ${}^{37}$K $\beta$-decay data set to allow the $\beta$ asymmetry with respect to nuclear spin to vary with $\beta$ energy $E_{\beta }$, we have gained s…
