“…They identified the Z c (3900)/Z c (3885) as the tetraquark state [cu][cd] with the quantum numbers 1 3 S 1 and J P = 1 + , and the Z c (4020)/Z c (4025) as the tetraquark state [cu][cd] with 1 5 S 2 and J P = 2 + . This is an extension of their previous study [486], where Deng, Ping, and Wang interpreted the Z c (3900) and Z c (4025)/Z c (4020) as the S-wave tetraquark states [cu][cd] with quantum numbers I = 1 and J = 1 and 2, respectively.…”

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.

“…Since the mass of Z ± c (3900) is very close to X(3872), it can be advised as the charged partner of the X(3872) in a tetraquark scenario. The properties of the Z ± c (3900) particle have been investigated with different theoretical models and approaches [18][19][20][21][22][23][24][25][26][27][28][29][30][31]. Although the spectroscopic properties of these particles have been studied adequately, the internal structure and nature of the X(3872) and Z ± c (3900) particles have not been fully understood yet.…”

The electromagnetic properties of the tetraquark state Zc(3900) are investigated in the diquarkantidiquark picture and its magnetic and quadrupole moments are extracted. To this end, the light-cone QCD sum rule in electromagnetic background field is used. The magnetic and quadrupole moments encode the spatial distributions of the charge and magnetization in the particle. The result obtained for the magnetic moment is quite large and can be measured in future experiments. We obtain a nonzero but small value for the quadrupole moment of Zc(3900) indicating a nonspherical charge distribution.
