Energy-independent PWA of the reaction $\gamma p\to K^{+}\Lambda$

Abstract

Using all recent data on the differential cross sections and spin observables for the reaction $\gamma p\to K^{+}\Lambda$, an energy-independent partial-wave analysis is performed. The analysis requires multipoles up to $L=2$; there is no evidence that the fit requires multipoles with $L=3$. At present the available data allow us to extract the dominant multipoles only. These are compatible with the multipoles obtained in the energy-dependent fit. This result supports the reliability of the Bonn-Gatchina energy-dependent results.
