Abstract

A Dalitz plot of 1.6 x 10 ⁶ 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 λ ₀ = 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.

A Measurement of the Branching Ratio of π ⁰ Dalitz Decay using K_L → π ⁰π ⁰π ⁰ Decays

Journal Article Abouzaid, E. ; Arenton, M. ; Barker, A. R. ; ... - Physical Review D

We present a measurement of B(π ⁰ → e ⁺e ^–γ)/ B(π ⁰ → γγ), the Dalitz branching ratio, using data taken in 1999 by the E832 KTeV experiment at Fermi National Accelerator Laboratory. We use neutral pions from fully reconstructed K_L decays in flight; the measurement is based on ~60 thousand K_L → π ⁰π ⁰π ⁰ → γγ γγ e ⁺e ^–γ decays. We normalize to K_L → π ⁰π ⁰π ⁰ → 6γ decays. We find B(π ⁰ → e ⁺e ^–γ)/ B(π ⁰ → γγ) (me ⁺e ^– > 15 MeV/c ²) = [3.920 ± 0.016(stat)more »« less

Journal Article Brandenburg, G.W. ; Johnson, W.B. ; Leith, D.W.G.S. ; ... - Phys. Rev., D, v. 8, no. 7, pp. 1978-1989

In a hydrogen bubble-chamber experiment with a KL beam we have measured the K/sup 0//sub mu 3//K/sup 0//sub e3/ branching ratio to be R = 0.741 plus or minus 0.044 and the slope of the f/sub +/ form factor to be lambda /sub +/ = 0.019 plus or minus 0.013. Th e data have been analyzed with a new variable, (p'T)/sup 2/, which isolates a sample of unique K/sub e3/ decays and is independent of the K/sub L/ beam momentum. These results are compatible with the predictions of K* dominance for f/sub +/ and the Callan-Treiman relation for f/ submore »« less
