A combined analysis of the K^+ -> π^0e^+ν and K^+ -> π^0μ^+ν decay modes
A model independent determination of the form factors ξ(q^2) and f(q^2) has been made, measuring, in intervals of q^2, the partial branching ratio Γ(K"μ"3^+)Γ(K"e"3^+) and using the results of the K"e"3^+ Dalitz plot density analysis. No experimental evidence has been f...

A combined analysis of the K^+ -> π^0e^+ν and K^+ -> π^0μ^+ν decay modes |
| abstract |
A model independent determination of the form factors ξ(q^2) and f(q^2) has been made, measuring, in intervals of q^2, the partial branching ratio Γ(K"μ"3^+)Γ(K"e"3^+) and using the results of the K"e"3^+ Dalitz plot density analysis. No experimental evidence has been found for a strong deviation from a linear q^2 dependence of the form factors. Within this approximation a combined analysis of the K"e"3^+ and K"μ"3^+ Dalitz plots gives the parameters λ"0 = -0.017 +/- 0.011 or alternatively ξ(0) = -1.3 +/- 0.7 and ξ(4.4 m"π^2) = -0.45 +/- 0.13, with in both cases a fitted value of λ"+ = 0.025 +/- 0.007. |

No experimental evidence has been found for a strong deviation from a linear q^2 dependence of the form factors. Within this approximation a combined analysis of the K"e"3^+ and K"μ"3^+ Dalitz plots gives the parameters λ"0 = -0.017 +/- 0.011 or alternatively ξ(0) = -1.3 +/- 0.7 and ξ(4.4 m"π^2) = -0.45 +/- 0.13, with in both cases a fitted value of λ"+ = 0.025 +/- 0.007. |

A model independent determination of the form factors ξ(q^2) and f(q^2) has been made, measuring, in intervals of q^2, the partial branching ratio Γ(K"μ"3^+)Γ(K"e"3^+) and using the results of the K"e"3^+ Dalitz plot density analysis. No experimental evidence has been found for a strong deviation from a linear q^2 dependence of the form factors. Within this approximation a combined analysis of the K"e"3^+ and K"μ"3^+ Dalitz plots gives the parameters λ"0 = -0.017 +/- 0.011 or alternatively ξ(0) = -1.3 +/- 0.7 and ξ(4.4 m"π^2) = -0.45 +/- 0.13, with in both cases a fitted value of λ"+ = 0.025 +/- 0.007. |
