Search for Pentaquark States Ξ(1860)0\Xi(1860)^0 and Ξ(1860)−−\Xi(1860)^{--} in Neutron--Carbon Interactions in the EXCHARM Experiment

Results of a search for strange pentaquark states $\Xi(1860)^0$ and $\Xi(1860)^{--}$ in neutron--carbon interactions at $\sim 51$ GeV mean energy of neutrons in the EXCHARM experiment have been presented. Such states in studied effective mass spectra $\Xi^-\pi^+$ and $\Xi^-\pi^-$ have not been observed. Upper limits of $\Xi(1860)^0$ and $\Xi(1860)^{--}$ production cross sections have been estimated

Associative Production of ϕ\phi Mesons and Neutral Kaons in the EXCHARM Experiment

Associative $\phi$-meson and neutral kaon production has been investigated in neutron--carbon interactions with the EXCHARM spectrometer at the Serpukhov accelerator. The cross section of inclusive associative $\phi$ and $K^0/\bar{K^0}$ production has been defined. The fraction of processes, permitted by Okubo--Zweig--Iizuka rule, was estimated in reactions with $\phi$-meson production
