“…Z + c (4200) and Z + (4240). Besides finding the evidence of Z + (4430) → π + J/ψ in theB 0 → K − π + J/ψ decay, Belle observed a new charged charmonium-like structure Z + c (4200) [107], which decays into J/ψπ + with a significance of 6.2σ. The measured mass and width of the Z + c (4200) are (4196 +31+17 −29−13 ) MeV and (370 +70+70 −70−132 ) MeV, respectively.…”

“…The measured mass and width of the Z + c (4200) are (4196 +31+17 −29−13 ) MeV and (370 +70+70 −70−132 ) MeV, respectively. It is obvious that the Z + c (4200) is a very broad structure [107]. The spin-parity quantum number of the Z + c (4200) favors J P = 1 + according to the analysis of Belle [107].…”

In the past decade many charmonium-like states were observed experimentally. Especially those charged charmoniumlike Z c states and bottomonium-like Z b states can not be accommodated within the naive quark model. These charged Z c states are good candidates of either the hidden-charm tetraquark states or molecules composed of a pair of charmed mesons. Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model. In this work, we review the current experimental progress and investigate various theoretical interpretations of these candidates of the multiquark states. We list the puzzles and theoretical challenges of these models when confronted with the experimental data. We also discuss possible future measurements which may distinguish the theoretical schemes on the underlying structures of the hidden-charm multiquark states.

The decays of B 0 s and B 0 s mesons into the J/ψK + K − final state are studied in the K + K − mass region above the φ(1020) meson in order to determine the resonant substructure and measure the CP -violating phase, φ s , the decay width, Γ s , and the width difference between light and heavy mass eigenstates, ∆Γ s . A decay-time dependent amplitude analysis is employed. The data sample corresponds to an integrated luminosity of 3 fb −1 produced in 7 and 8 TeV pp collisions at the LHC, collected by the LHCb experiment. The measurement determines φ s = 119 ± 107 ± 34 mrad. A combination with previous LHCb measurements using similar decays into the J/ψπ + π − and J/ψφ(1020) final states gives φ s = 1 ± 37 mrad, consistent with the Standard Model prediction.
