“…BESIII named this structure as the Z c (3885) since its measured mass (see Table 8) was slightly lower than that of the Z c (3900) measured in the J/ψπ channel by BESIII [64] and Belle [124]. However, the measured mass and width of the Z c (3885) [159] were consistent with those of the Z c (3900) state obtained by Xiao et al [61]. Later in Ref.…”

The hidden-charm pentaquark and tetraquark states

et al. 2016

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.

To explore cosmic matter in the laboratory -this fascinating research prospect becomes available in 2018 at the Facility for Antiproton and Ion Research, FAIR. The new facility is being constructed within the next five years adjacent to the existing accelerator complex of the GSI Helmholtz Centre for Heavy Ion Research at Darmstadt/Germany, expanding the research goals and technical possibilities substantially. This includes new insights into the dynamics of supernovae depending on the properties of short-lived neutron-rich nuclei which will be investigated with intense rare isotope beams. New insights will be provided into the interior of stars by exploring dense plasmas with intense heavy-ion beams combined with a high-performance laser -or into neutron star cores by probing the highest baryon densities in relativistic nucleusnucleus collisions at unprecedented collision rates. To the latter, the properties of hadrons play an important part which will be systematically studied by high precision hadron spectroscopy with antiproton beams at unmatched intensities. The worldwide unique accelerator and experimental facilities of FAIR will open the way for a broad spectrum of unprecedented fore-front research supplying a large variety of experiments in hadron, nuclear, atomic and plasma physics as well as biomedical and material science which will be briefly described in this article.

On the two-body decay processes of the predicted three-body K*(4307) resonance

In a recent theoretical work, Phys. Lett. B785, 112 (2018), we proposed that a K * resonance with hidden charm content arises from the KDD * dynamics, where the DD * system is treated as a Z c (3900) or X(3872). With the motivation of determining its further properties, which can be observed in experiments, we now present a calculation of the decay processes of this K * , namely K * (4307), to two-body channels. Particularly, we consider the decay channels J/ψK * (892),DD s ,DD * s andD * D * s . The mechanisms of the decay to these channels involve triangular loops and are a consequence of the internal structure of the state. Thus, the values found for the decay widths of the proposed K * (4307) are related to its nature and should be valuable for carrying on an experimental study of the K * (4307). A K * state with such a mass (in the charmonium region) and quantum numbers is a clear manifestation of an exotic meson, since, having hidden charm (i.e., a cc pair), its mass and quantum numbers can not be explained within a quark-antiquark description.
