Abstract
The reaction [Formula presented] was studied at Jefferson Laboratory using a tagged photon beam with an energy range of 3–5.47 GeV. A narrow baryon state with strangeness [Formula presented] and mass [Formula presented] was observed in the [Formula presented] invariant mass spectrum. The peak’s width is consistent with the CLAS resolution ([Formula presented]), and its statistical significance is [Formula presented]. A baryon with positive strangeness has exotic structure and cannot be described in the framework of the naive constituent quark model. The mass of the observed state is consistent with the mass predicted by the chiral soliton model for the [Formula presented] baryon. In addition, the [Formula presented] invariant mass distribution was analyzed in the reaction [Formula presented] with high statistics in search of doubly charged exotic baryon states. No resonance structures were found in this spectrum.
