FIG.1: Processes contributing to the K_{L}>pi^{+}e^{+}nu e^{+}e^{} decay: the virtural photon comes (a) from the charged pion, (b) from the K_{e3} electron, and (c) from the kaon decay vertex. The process (c) includes the structure dependent (SD) amplitudes. The exchange diagrams have veen omitted for clarity.

FIG.2: The k_{+0} distributiosn for data and MC after all analysis requirements except for 'k_{+0}'. The vertical line and arrow show the accepted region for the signal candidates (k_{+0} < 0.002 GeV^{2}/c^{2}). The disagreement betweendata and MC in the range k_{+0}>0.02GeV^{2}/c^{2} does not affect the background estimate in the signal region. DataMC comparisons between many other distributions in teh accepted k_{+0} region show good agreement leading us to conclude that the backgrounds are wellmodeled in the region of interest.

FIG.3(a): Comparisons of the t_{\bot}M_{pi}^{2} distributions for data (dots) and MC (histogram), (a) with MCLO. The datatoMC ratios at the bottom are fit to a straight line.

FIG.3(b): Comparisons of the t_{\bot}M_{pi}^{2} distributions for data (dots) and MC (histogram), (b) with MCNLO(p^{4}). The datatoMC ratios at the bottom are fit to a straight line.
