Global parametrizations of $π π$ scattering with dispersive constraints: Beyond the S0 wave

J. R. Peláez, P. Rabán, J. Ruiz de Elvira

We provide new global parametrizations of $π π \to π π$ 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 ea…

Dispersive $π π \to K K ˉ$ amplitude and giant CP violation in B to three light-meson decays at LHCb

R. Alvarez Garrote, J. Cuervo, P. C. Magalhães +2

The LHCb collaboration has recently reported the largest CP violation effect from a single amplitude, as well as other giant CP asymmetries in several $B$ -meson decays into three c…

Dispersive $π K \to π K$ and $π π \to K K ˉ$ amplitudes from scattering data, threshold parameters and the lightest strange resonance $κ$ or $K_{0}^{*} (700)$

J. R. Peláez, A. Rodas

We discuss the simultaneous dispersive analyses of $π K \to π K$ and $π π \to K K ˉ$ scattering data and the $κ / K_{0}^{*} (700)$ resonance. The unprecedented statistics of present and fu…

Global parameterization of $π π$ scattering up to 2 GeV

J. R. Pelaez, A. Rodas, J. Ruiz de Elvira

We provide global parameterizations of $π π$ scattering $S 0$ and $P$ partial waves up to roughly 2 GeV for phenomenological use. These parameterizations describe the output and unce…

$π π \to K K ˉ$ scattering up to 1.47 GeV with hyperbolic dispersion relations

J. R. Pelaez, A. Rodas

In this work we provide a dispersive analysis of $π π \to K K ˉ$ scattering. For this purpose we present a set of partial-wave hyperbolic dispersion relations using a fami…

Calculation of resonances from $K π$ scattering

A. Rodas, J. R. Pelaez, J. Ruiz de Elvira

We present a determination of the mass, width and coupling of the strange resonances appearing in pion-kaon scattering below 1.8 GeV, namely the much debated $K_{0}^{*} (800)$ or $κ$ , t…
