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…
