Construction of the $a_{4}$ family

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

The COMPASS Collaboration recently reported \sout{the observation of a new resonance, $a_{4} (2610)$ }{\blue{a new broad $J^{P C} = 4^{++}$ structure, denoted as $a_{4} (2610)$ }}, which has…

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…

High spin kaons

Ya-Rong Wang, Hao Chen, Xiao-Hai Liu +1

The COMPASS Collaboration recently reported the observation of strange-meson spectra in the reaction $K^{-} + p \to K^{-} I ¨ ^{-} I ¨ ^{+} + p$ and found $K_{3}$ and $K_{4}$ states, with masses o…
