“…Beyond the allowed approximation, the hadronic weak current contains additional recoil-order form factors [38,39,41,42]. Some of these terms are classified as secondclass, based on their transformation properties under the G-parity operation [38,43]. Within the limit of perfect isospin symmetry, second-class currents are forbidden in the standard model.…”

We used the 8π γ-ray spectrometer at the TRIUMF-ISAC radiocative ion beam facility to obtain high-precision branching ratios for 19 Ne β + decay to excited states in 19 F. Together with other previous work, our measurements determine the superallowed 1/2 + → 1/2 + beta branch to the ground state in 19 F to be 99.9878(7)%, which is three times more precise than known previously. The implications of these measurements for testing a variety of weak interaction symmetries are discussed briefly.

“…where V µ transforms as a Lorentz vector and A µ as an axial vector. In the absence of second-class currents (with the opposite behaviour) [49,50], we can require the same thing from the radiative corrections. Specifically, all terms discussed in the following sections must individually transform as first-class currents.…”

Effective-field theory analysis of the τ The rare τ − → η ( ) π − ν τ decays, which are suppressed by G-parity in the Standard Model (SM), can be sensitive to the effects of new interactions. We study the sensitivity of different observables of these decays in the framework of an effective field theory that includes the most general interactions between SM fields up to dimension six, assuming massless neutrinos. Owing to the strong suppression of the SM isospin breaking amplitudes, we find that the different observables would allow to set constraints on scalar interactions that are stronger than those coming from other low-energy observables.
