The study of hyperon resonances has entered a new era of precision with advent of high-statistics photoproduction data from the CLAS detector at Jefferson Lab. These data have multi-particle final states, allowing clean identification of exclusive reactions associated with strange mesons and baryons. Examples of physics results are: evidence for isospin interference in the decay of the Λ ( 1405 ) resonance; a strong suggestion of meson cloud effects in the structure of the Σ ( 1385 ) resonance; data from K ⁎ photoproduction that will test the existence of the purported K 0 ( 800 ) meson. Properties of other hyperon resonances will also be studied in the near future.
