“…Later, the Y(4260) was confirmed by both the CLEO [60] and Belle [119] collaborations in the same process. Besides the above experimental measurement of the Y(4260), CLEO analyzed the data at the CESR e + e − collisions at √ s = 3.97 − 4.26 GeV [120]. They confirmed the Y(4260) → π + π − J/ψ decay channel at 11σ significance and observed a new decay mode Y(4260) → π 0 π 0 J/ψ at 5.1σ significance.…”

“…The observed decay modes of the Y(4260) include J/ψπ + π − [62,60,119], J/ψπ 0 π 0 [120], and possibly J/ψK + K − [120]. Additionally, the dipion mass distribution of Y(4260) → π + π − J/ψ was measured [62,60,119,123], and there exists an enhancement around 980 MeV, which may arise from the scalar meson f 0 (980).…”

The hidden-charm pentaquark and tetraquark states

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.

“…In 2005, Y(4260) was first observed by BABAR Collaboration in e + e − → J/ψππ [1], and was later confirmed by Belle [2] and CLEO-c collaborations [3] in the same channel. Although there have been a lot of efforts on understanding the nature of Y(4260), its mysterious property has imposed a challenge for the community.…”

In this proceeding we present our recent work on the study of Y (4260) (4260) and the wavefunction renormalization constant. The relation between the long-rangedDD 1 (2420) + c.c. molecular component and a compact cc component can then be determined according to Weinberg's compositeness theorem. Our study suggests that the Y(4260) has a dominantDD 1 + c.c. component which is essential for understanding so far the available experimental observables, while the small cc component account for naturally the production of Y(4260) as a consequence of the heavy quark spin symmetry breaking.
