摘要
The [Formula presented] reaction on [Formula presented] has been studied by measuring both [Formula presented] and [Formula presented] at forward angles. A sharp baryon resonance peak was observed at [Formula presented] with a width smaller than [Formula presented] and a Gaussian significance of [Formula presented]. The strangeness quantum number ([Formula presented]) of the baryon resonance is [Formula presented]. It can be interpreted as a molecular meson-baryon resonance or alternatively as an exotic five-quark state ([Formula presented]) that decays into a [Formula presented] and a neutron. The resonance is consistent with the lowest member of an antidecuplet of baryons predicted by the chiral soliton model.
