Title: Measurement of the Form Factors in the Decay K^o_L → πμν

Abstract

A Dalitz plot of 1.6 x 10⁶ K^o_L → πμν decays has been studied to measure the t dependence of the vector and scalar form factors. Here, the observed slopes, λ₊ = 0.030 ± 0.003 and λ₀ = 0.020 ± 0.003, are compatible with current algebra and soft pion predictions, μ - e universality, and K* (890) dominance of the vector form factor.

Measurement of the form factors in the decay K/sub L/$sup 0$ $Yields$ $pi$$mu$$nu$

Journal Article Donaldson, G ; Fryberger, D ; Hitlin, D ; ... - Phys. Rev. Lett., v. 31, no. 5, pp. 337-340

>A Dalitz plot of l.6xl0/sup 6/K/sub L//sup 0/ yields pi mu nu decays has been stu died to measure the t dependence of the vector and scalar form factors. The observed slopes, lambda /sub +/ =0.030 plus or minus 0.003 and lambda /sub 0/=0.020 plus or minus 0.003, are com patible with current- algebra and soft-pion predictions, mu -e universality, and K*(890) dominance of the vector form factor.

Measurement of the f/sub +/ form factor in K/sup 0//sub L/. -->. pi. /sup + -/e/sup - +/v decays using a large hydrogen bubble chamber

Journal Article Engler, A ; Keyes, G S ; Kraemer, R W ; ... - Phys. Rev., D; (United States)

The decay K/sup 0//sub L/ ..-->.. ..pi..e..nu.. was studied in an experiment using the Argonne 12-ft bubble chamber exposed to a K/sup 0//sub L/ beam of momentum 550 +- 35 MeV/c. Use of the monochromatic beam and the large chamber volume allowed the selection of about 12 000 K/sup 0//sub e/3 events, containing a small ((5.3 +- 0.5) %) and well understood background from K/sup 0//sub mu3/ decay. The main feature of this experiment is the good acceptance over the Dalitz plot which minimizes possible systematic errors in the determination of the vector form factor f/sub +/(q/sup 2/).

A Study of the Decay K°_L → πμν

Technical Report Hill, D. G.

We report results from a Dalitz plot analysis of 16386 K°_μ3 candidates obtained in an experiment with high efficiency across the Dalitz plot and very low background. We measure the vector and scalar form factors and obtain the following values for the linear expansion parameters: λ₊ = 0.028 ± 0.011, λ_o = 0.039 ± 0.010.

$Λ_{c} \to N$ form factors from lattice QCD and phenomenology of $Λ_{c} \to n ℓ^{+} ν_{ℓ}$ and $Λ_{c} \to p μ^{+} μ^{-}$ decays

Journal Article Meinel, Stefan - Physical Review D

We report on a lattice QCD determination of the Λ_c→N vector, axial vector, and tensor form factors. Here, the calculation was performed with 2+1 flavors of domain wall fermions at lattice spacings of a≈0.11 and 0.085 fm and pion masses in the range 230 MeV≲ m_π ≲ 350 MeV. The form factors are extrapolated to the continuum limit and the physical pion mass using modified z expansions. The rates of the charged-current decays Λ_c→ne+ν_e and Λ_c→nμ+ν_μ are predicted to be (0.405 ± 0.016_stat ± 0.020_syst)|V_cd|²ps^₋1 and (0.396 ± 0.016_stat ± 0.020_syst)|V_cd|²ps^₋1, respectively.
