| Résumé : | A model independent determination of the form factors ξ(q2) and f(q2) has been made, measuring, in intervals of q2, the partial branching ratio Γ (Kμ3+) Γ(Ke3+) and using the results of the Ke3+ Dalitz plot density analysis. No experimental evidence has been found for a strong deviation from a linear q2 dependence of the form factors. Within this approximation a combined analysis of the Ke3+ and Kμ3+ Dalitz plots gives the parameters λ0 = -0.017 ± 0.011 or alternatively ξ(0) = -1.3 ± 0.7 and ξ(4.4 mπ2) = -0.45 ± 0.13, with in both cases a fitted value of λ+ = 0.025 ± 0.007. © 1974. |
