Speaker
Description
Charged (non-zero isospin) charmonium-like states hold a unique position
in hadron spectroscopy, as their charged nature precludes a pure ccbar quark
configuration, making them compelling candidates for exotic hadrons or tetraquark
structures. This talk highlights recent progress in the investigation of charged
charmonium-like states at BESIII, leveraging the experiment’s world-leading data
samples and advanced analysis techniques. Key topics include the application of
partial wave analysis to disentangle overlapping resonant contributions and the
incorporation of coupled-channel effects to account for interactions between
open-charm thresholds and exotic states. These novel methodologies have uncovered
new insights into the nature of these exotic systems, shedding light on their
production mechanisms and internal dynamics. Results from BESIII’s latest analyses
will be presented, with a focus on their implications for understanding
non-conventional QCD phenomena and the broader landscape of exotic hadrons.
