| dc.description | We investigate the photoproduction of $K^*$ vector meson for the study of the $Λ(1405)$ resonance. The invariant mass distribution of $πΣ$ shows a different shape from the nominal one, peaking at 1420 MeV. This is considered as a consequence of the double pole structure of $Λ(1405)$, predicted in the chiral unitary model. Combined with other reactions, such as $π^- p \to K^0 πΣ$, experimental confirmation of this fact will reveal a novel structure of the $Λ(1405)$ state. | |
