Abstract
The electroweak interaction in the Standard Model (SM) is described by a pure vector-axial-vector structure, though any Lorentz-invariant component could contribute. In this work, we present the most precise measurement of tensor currents in the low-energy regime by examining the - correlation of trapped Li ions with the Beta-decay Paul Trap. We find at for the case of coupling to right-handed neutrinos , which is consistent with the SM prediction.
