摘要：

The validity of the V-A theory in Kμ3+ decay is checked and the contribution of the tensor interaction is found to be compatible with zero. A consistent interpretation of measurements of the Kμ3+ Dalit plot density, of the muon polarization in Kμ3+ decay, and of the Kμ3+ Ke3+ branching ratio is found to be possible. From a study of the relative magnitude and four-momentum transfer dependence of the vector form factors, the best fit to the combined data is λ+ = 0.060-0.017+0.01, Λ = -0.01-0.11+0.13, and ξ(5mπ2) = -0.93 ± 0.23. The results are compared to current theoretical predictions. © 1969.
