The inclusion of elastic rescattering and annihilation of quark–antiquarks pairs in final state can explain the t-dependency for cross-section ratio of η and η′ mesons in charge exchange reaction. The estimation for mixing angle η − η′ with isoscalar states ūu + dd and hidden strangeness ss has been obtained. The consistent description of η and η′ meson outputs in B0, Bs0 and J/ψ decays was also considered.
