Construction of the $a_{4}$ family

Ya-Rong Wang, Cheng-Qun Pang, Hao Chen +1

The COMPASS Collaboration recently reported a new broad $J^{P C} = 4^{++}$ structure, denoted as $a_{4} (2610)$ , which has sparked our interest in studying the $a_{4}$ family with $I^GJ^{P…

New Types of Hydrogenlike matter Composed of Electron(s) and Meson(s)

Jun-Feng Wang, Zi-Yue Cui, Cheng-Qun Pang +1

In the present work, we predict the existence of new types of hydrogenlike matter, including hydrogenlike atoms ( $π^{+} e^{-}$ , $K^{+} e^{-}$ , $D^{+} e^{-}$ ), hydrogenlike molecular ions ($π^+π^+…

Spectroscopy and Decay Properties of Excited Charmonium States

Zi-Yue Cui, Hao Chen, Cheng-Qun Pang +1

In this work, we investigate the mass spectra of excited charmonia employing a nonrelativistic potential model with screening effect, and analyze their two-body strong decay, two-p…

Arrangement for $K_{2}^{*}$ meson family

Ting-yan Li, Ya-rong Wang, Cheng-qun Pang

Two observed structures with $M = 1868 \pm 8_{- 57}^{+ 40}$ MeV and $M = 2073 \pm 9 4_{- 240}^{+ 245}$ MeV are the same states ( $K_{2}^{*} (1980)$ ) in PDG.The analysis of the mass spectrum a…
