Associated production of ϕ mesons and neutral kaons in the EXCHARM experiment

2006

The features of the associated production of ϕ mesons and neutral kaons are studied on the basis of data obtained at the EXCHARM spectrometer (Serpukhov accelerator) in neutron—carbon interactions at neutron-beam energies in the range 20–70 GeV. The cross section for the inclusive associated production of ϕ and K 0/-K 0 is obtained. The fraction of processes allowed by the Okubo-Zweig-Iizuka rule is estimated in the reactions of ϕ-meson inclusive production.
