Global parameterizations of $\pi\pi$ scattering with dispersive
constraints: beyond the S0 wave
We provide new global parameterizations of $\pi\pi$ scattering for the S2, P, D, F, and G partial waves up to at least 1.8 GeV, easy to implement for phenomenological use. With earlier S0-wave parameterizations, slightly updated here, they reproduce previous partial wave dispersion analyses up to the $\pi\omega$ threshold. In …
