Abstract The first ever observation of the decay process B{sup 0} → J/ψη′ is described. The branching ratios were measured for the decay processes B{sub (s)} → J/ψη(′), and the η–η′ mixing angles were determined on this basis. The first indication of the occurrence of the decay process B{sub s} → ψ(2S)η′ is presented. The respective analysis was performed on the basis of data accumulated with the LHCb detector in proton–proton collisions at the c.m. collision energies of 7 and 8 TeV and the integrated luminosity of 3 fb{sup −1}.
