"Improved KL->pi^+-e^-+nu Form Factor and Phase Space Integral with Reduced Model Uncertainty"

• dGdt.eps, dGdt.pdf
  Fig.1: calculated t-distribution, dGamma/dt, for KL->pi^+-e^-+nu phase space (dashed), and for phase space modified by the form factor in [1] (solid line).

• phase_ratios.eps, phase_ratios.pdf
  Fig.2: Calculated phase space ratios versus t/M²_pi, (dGamma/dt)^model / (dGamma/dt)^lin, where model = pole (Eq. 3), quadratic-t (Eq. 2) and quadratic-z (Eq. 5). The reference model (dGamma/dt)^lin uses f₊^lin(t) = 1 + 0.0283 t/M²_pi.
