Abstract

The new single-channel, single-energy partial-wave analysis method based on a simultaneous use of amplitude and partial-wave analysis called AA-PWA, developed and tested on eta photoproduction in [Phys. Rev. C 102, 064609 (2020)] is applied to the K+Lambda photoproduction for the center-of-mass energy range of 1625 MeV < W < 2296 MeV. A complete set of multipoles has been created. The advantages of the method have been confirmed and a comparison with the only existing single-energy partial-wave analysis of K+Lambda photoproduction given in [Phys. Rev. Lett. 119, 062004 (2017), Eur. Phys. J. A 53, 242 (2017)] is presented. We confirm the size and shape of Bonn-Gatchina multipoles, but we do not confirm the unambiguous interpretation of the structure in the M1- multipole as a N (1880)1/2(+) resonance. The decisive role of the self-consistency of the world database is emphasized.
