Popis: The most recent results of investigations into exotic charmonium states in the LHCb experiment are presented. The quantum numbers of the X(3872) state were measured, a piece of evidence for the decay X(3872)→ ψ(2S)γ was obtained, and the existence of the Z(4430)− state was confirmed. The analyses that led to these results were based on data accumulated by the LHCb detector in proton–proton collisions at the c.m. energies of 7 and 8 TeV. The data sample used corresponded to integrated luminosities between 1 and 3 fb−1.
