Abstract
A new analysis of \(K\varLambda \) photoproduction is presented, including the latest data measured at Jefferson Lab and other facilities. Evidence for two states has been found, the \(N(1900)3/2^+\) and \(N(2060)5/2^-\) resonances that have been seen in other analysis. Future extensions are discussed like the use of model selection techniques to achieve a minimal resonance content of the amplitude. Also, conceptual aspects like three-body unitarity are highlighted that can help to provide a connection between phenomenology and ab-initio lattice QCD calculations.
