Parallel session B7
- Manuel Lorenz (Goethe University Frankfurt)
The pseudoscalar glueball has seen a revival of interest following the observation of the pseudoscalar resonances $X(2370)$ and $X(2600)$ at BESIII, which are among the most promising candidates. On the theory side, the pseudoscalar glueball is deeply connected to the chiral anomaly, a fundamental feature of QCD. In this talk, we confront theoretical expectations with experimental findings and...
In this talk, I will first introduce the transverse momentum factorization scheme, and then discuss how to use dispersion relations and form factor data to achieve an accurate extraction of the fine structure (light-cone distribution amplitudes) of light hadrons, including $\pi,K,\eta^{(\prime)}$ mesons and proton.
The BESIII experiment, with its unique data samples collected in the √s = 4.0 – 4.95 GeV region, continues to provide important inputs for the understanding of charmonium and exotic XYZ states. In this talk, we will present recent activities related to X- and Z-states. Key results include a multi-channel joint analysis of the Zc(4020), a search for a charmonium-like state with exotic quantum...
