Associated production of Phi mesons and strange particles and double Phi meson production

Associated production ofφ-mesons and strange particles by neutrons at energies of 30–70 GeV has been analysed. It has been found that at least 67% of inclusiveφ-meson production in the kinematic regionxF>0.1 andpT<1 GeV/c proceeds via OZI-allowed processes with extra strange particles. Doubleφ-meson production has also been observed and its cross section in the full kinematic region is estimated to be 15 ± 9μb.
