Existence of the and three-body molecular states
Yan-Ke Chen, Lu Meng, Jun-Zhang Wang +1
We investigate the existence of the three-body molecular state composed of within the one-boson-exchange (OBE) model. A major challenge is that while the pseudoscal…
Electromagnetic polarizabilities of the triplet hadrons in heavy hadron chiral perturbation theory
Hao Dang, Liang-Zhen Wen, Yan-Ke Chen +1
We investigate the electromagnetic polarizabilities of singly heavy mesons and doubly heavy baryons within the framework of heavy hadron chiral perturbation theory up to $\mathcal{…
Tetraquark states in the quark model
Wei-Lin Wu, Yan-Ke Chen, Yao Ma +2
We perform systematical investigations of heavy flavor tetraquark systems, including fully heavy (), doubly heavy (), and…
Electromagnetic polarizabilities of the spin- baryons in heavy baryon chiral perturbation theory
Liang-Zhen Wen, Yan-Ke Chen, Lu Meng +1
We employ Heavy Baryon Chiral Perturbation Theory (HBPT), a non-relativistic effective field theory that treats baryons as heavy static sources, to calculate the electromagneti…
Uncovering the mystery of with the coupled-channel dynamics
Jun-Zhang Wang, Zi-Yang Lin, Yan-Ke Chen +2
The , as the first and the most crucial member in the exotic charmoniumlike family, has been studied for a long time. However, its dynamical origin, whether stemming…
Electromagnetic polarizabilities of the spin- singly heavy baryons in heavy baryon chiral perturbation theory
Yan-Ke Chen, Liang-Zhen Wen, Lu Meng +1
We calculate the electromagnetic polarizabilities of the spin- singly heavy baryons in the heavy baryon chiral perturbation theory up to . We estimat…
