Reevaluating the $a_{1} (1420)$ enhancement and its molecular partners in the low-lying axial-vector meson spectrum

Mao-Jun Yan, Chun-Sheng An, Cheng-Rong Deng

We assess possible axial-vector states with $G$ -parity $(G = \pm 1)$ dynamically generated by pseudoscalar-vector interactions in coupled channels, driven by the Weinberg-…

New spectrum of charm-strange meson with constituent quark model $c s ˉ$ contributions

Liu-Lin Wang, Xing-Meng Zhao, Xiao-Hai Liu +1

We systematically investigate the $S$ -wave interactions between Nambu-Goldstone bosons (NGBs) and charmed mesons in the $(S, I) = (1, 0)$ sector using the chiral unitary approach. The…

The low-lying light tetraquark states with quantum numbers $J^{P} = 0^{+}$ , $1^{+}$ and $2^{+}$

Hao Wu, Mao-Jun Yan, Chun-Sheng An +1

The low-lying light tetraquark states are investigated in the non-relativistic quark model (NRQM) including the pseudoscalar meson exchange, where two different confinement potenti…

Hydrogenlike molecules composed of $D_{1} D_{1}$ , $D_{1} D_{2}^{}$ and $D_{2}^{} D_{2}^{*}$

Hu-Hua He, Mao-Jun Yan, Chun-Sheng An +1

We systematically explore the S-wave $D_{1} D_{1}$ , $D_{1} D_{2}^{*}$ and $D_{2}^{*} D_{2}^{*}$ states with various isospin-spin-orbit ( $I S L$ ) configurations in the quark model. We propose nine stable…
