Global parameterization of [Formula: see text] scattering up to 2 [Formula: see text]
We provide global parameterizations of [Formula: see text] scattering S0 and P partial waves up to roughly 2 GeV for phenomenological use. These parameterizations describe the output and uncertainties of previous partial-wave dispersive analyses of [Formula: see text] , both in the real axis up to 1...

Sumario: | We provide global parameterizations of [Formula: see text] scattering S0 and P partial waves up to roughly 2 GeV for phenomenological use. These parameterizations describe the output and uncertainties of previous partial-wave dispersive analyses of [Formula: see text] , both in the real axis up to 1.12 [Formula: see text] and in the complex plane within their applicability region, while also fulfilling forward dispersion relations up to 1.43 [Formula: see text] . Above that energy we just describe the available experimental data. Moreover, the analytic continuations of these global parameterizations also describe accurately the dispersive determinations of the [Formula: see text] , [Formula: see text] and [Formula: see text] pole parameters. |
