none968siThe decays B0s → J/ψ π+ π− K+ K− are studied using a data set corresponding to an integrated luminosity of 9 fb^−1, collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of 7, 8 and 13 TeV. The decays B0s → J/ψ K*0 anti-K*0 and B0s → χc1(3872) K+ K−, where the K+ K− pair does not originate from a ϕ meson, are observed for the first time. Precise measurements of the ratios of branching fractions between intermediate χc1(3872) ϕ, J/ψ K*0 anti-K*0, ψ(2S) ϕ and χc1(3872) K+ K− states are reported. A structure, denoted as X(4740), is observed in the J/ψ ϕ mass spectrum and, assuming a Breit-Wigner parameterisation, its mass and width are determined to be m_X(4740) = 4741 ± 6 ± 6 MeV/c^2, Γ_X(4740) = 53 ...
