Title: Partial-wave analysis of γ p K + Λ using a multichannel framework

Abstract

Results from a partial-wave analysis of the reaction γp→K+Λ are introduced. The reaction is dominated by the S 11(1650) and P 13(1720) resonances at low energies and by P 13(1900) at higher energies. There are small contributions from all amplitudes up to and including G 17, with F 17 necessary for obtaining a good fit of several of the spin observables. We present evidence for P 11(1880), D 13(2120), and D 15(2080) resonances, as well as a possible F 17 resonance near 2300 MeV, which is expected from quark-model predictions. Some predictions for γn→K 0Λ are also covered.
