Dispersive analysis of the Primakoff reaction $$\gamma K \rightarrow K \pi $$ γ K → K π

Abstract We provide a dispersion-theoretical representation of the reaction amplitudes $$\gamma K\rightarrow K \pi $$ γ K → K π in all charge channels, based on modern pion–kaon P-wave phase shift input. Crossed-channel singularities are fixed from phenomenology as far as possible. We demonstrate ho...
