| 摘 要： | In the framework of the improved chromomagnetic interaction model, we complete a systematic study of the S-wave tetraquark states ■ ( Q = c, b, and q = u, d, s) with different quantum numbers: JPC= 0(+(+)), 1(+(±)),and 2(+(+)). The mass spectra of tetraquark states are predicted, and the possible decay channels are analyzed by considering both the angular momentum and C-parity conservation. The recently observed hidden-charm tetraquark states with stra...
