Multipole analysis of kaon photoproduction data

TL;DR

This paper applies multipole analysis techniques to kaon photoproduction data, comparing results with models and previous studies, revealing areas of agreement and instability due to limited data.

Contribution

It extends multipole analysis methods from pion to kaon photoproduction, evaluating their effectiveness and stability with current experimental data.

Findings

Some multipoles agree with phenomenological models

Other multipoles are unstable with current data

Results highlight the need for more data for stability

Abstract

Methods used in the multipole analysis of low-energy pion-photoproduction data have been tested against the database of kaon-photoproduction measurements. Results for some multipoles are in qualitative agreement with existing phenomenological models, while others are unstable, given the present database. These findings are compared to those of previous studies.
