The $K (1690)$ signal from COMPASS as a strange hybrid state

Bing Chen, Ri-Qing Qian, Xiang Liu

A pseudoscalar resonance structure, denoted as the $K (1690)$ , was recently discovered by the COMPASS Collaboration in the scattering reaction $K^{-} + p \to K^{-} π^{-} π^{+} + p$ . If the $K(1690…

Revisiting charmonium hybrid spectroscopy

Ri-Qing Qian, Bing Chen, Xiang Liu

Hadrons with explicit gluonic degrees of freedom, such as charmonium hybrids, are key to understanding nonperturbative behavior of strong interaction, yet they remain experimentall…

Discovery potential of charmonium $2 P$ states through the $e^{+} e^{-} \to I^^{3} D D ˉ$ processes

Tian-Le Gao, Ri-Qing Qian, Xiang Liu

In this work, we investigate the production of charmonium $2 P$ states via the $e^{+} e^{-} \to I^^{3} D D ˉ$ process at $s = 4.23$ GeV. Using the measured cross-section data for $e^…

Finding Interaction Mechanism between Exotic Molecule and Conventional Hadron

Ri-Qing Qian, Fu-Lai Wang, Xiang Liu

An intriguing and important question arises: how do hadronic molecules interact with conventional hadrons? In this work, we propose a novel mechanism to address this issue, focusin…

Spectroscopic Properties of Double-Strangeness Molecular Tetraquarks

Fu-Lai Wang, Si-Qiang Luo, Ri-Qing Qian +1

Inspired by recent advances in the study of the $K^{(*)} K ˉ^{(*)}$ molecular tetraquarks and the $H$ -dibaryon, we focus on the spectroscopic properties of the $\bar K^{(*)} \ba…
