3 Fig. 3. The $I=1$ total cross section from chiral perturbation theory up to the next-to-leading-order comparison with the experimental data [24–27,30,31]. The partial wave contributions are plotted by dashed lines. The horizontal axis means the $K^{+}$ meson incident momentum in the lab frame $p_{{\rm lab}}$ in units of MeV/$c$ and the vertical axis means the total cross section $\sigma$ in units of mb.
