Spin-orbit amplitudes for decays with arbitrary spin
Xiao-yu Li, Xiang-Kun Dong, Hao-Jie Jing
In this paper, we propose a method to construct the decay amplitudes in the orbital () and spin () coupling scheme for particles with arbitrary spins. For the decay…
Understanding the and charmonium(-like) states near 3.9 GeV
Teng Ji, Xiang-Kun Dong, Miguel Albaladejo +4
We propose that the observed in the channel is the same state as the , and the , observed in the channel, is an -wave $D_s…
Chromopolarizabilities of fully-heavy baryons
Xiang-Kun Dong, Feng-Kun Guo, Alexey Nefediev +1
We compute the chromopolarizabilities of the fully heavy baryons () in the framework of potential nonrelativistic quantum chromodynamics. At leading order, the…
Establishing the heavy quark spin and light flavor molecular multiplets of the , and
Teng Ji, Xiang-Kun Dong, Miguel Albaladejo +3
Recently, the LHCb Collaboration reported a near-threshold enhancement, , in the invariant mass distribution. We show that the data can be well described by e…
Prediction of a narrow exotic hadronic state with quantum numbers
Teng Ji, Xiang-Kun Dong, Feng-Kun Guo +1
Lots of charmonium-like structures have been observed in the last two decades. Most of them have quantum numbers that can be formed by a pair of charm and anticharm quarks, thus it…
Interpretation of the as a c.c. molecule
Xiang-Kun Dong, Yong-Hui Lin, Bing-Song Zou
An exotic state with , denoted by , was observed by BESIII collaboration recently in . The fact that its mass is just below the threshold of…
