Abstract

We report observation of a narrow peak structure at $\sim$ 1.54 GeV with a Gaussian width $σ = 6$ MeV in the missing mass of $K_{S}$ in the reaction $γ + p \to p K_{S} K_{L}$ . The observed structure may be due to the interference between a strange (or antistrange) baryon resonance in the $p K_{L}$ system and the $φ (K_{S} K_{L})$ photoproduction leading to the same final state. The statistical significance of the observed excess of events estimated as the log-likelihood ratio of the resonant signal + background hypothesis and the $φ$ -production-based background-only hypothesis corresponds to $5.3 σ$ .
