As a particle with hidden strangeness, [phi] meson can be produced without an associated hyperon. Recently, in the reaction [gamma]p [right arrow] p[phi]([K.sub.S][K.sub.L]), a photoproduction cross-section of the [phi] meson in its neutral decay mode was measured by the CLAS Collaboration.
Such hyper-nuclei, called hyperons, can be created in laboratories but survive only for a short time.
