Determination of the $Z_{c} (3900)$ and the $Z_{cs} (3985)$ states from joint analysis of experimental and lattice data

Yun-Hua Chen, Meng-Lin Du, Feng-Kun Guo

We present a unified analysis of the $Z_{c} (3900)$ and $Z_{cs} (3985)$ states considering both experimental and lattice data. The study simultaneously includes the processes $e^+e^- \…

Decoding the structure near the $π^{+} π^{-}$ mass threshold in $ψ (3686) \to J / ψ π^{+} π^{-}$ decays

Yun-Hua Chen, Xiang-Kun Dong, Feng-Kun Guo +2

In light of recent high-precision data taken by the BESIII Collaboration, we reconsider the dipion transition $ψ (3686) \to J / ψ π^{+} π^{-}$ . The strong pion-pion final-state inte…

Structural Obstructions in Fixed-Shift Prime Correlations via Mellin-Laplace Kernels

Yung-Hua Chen

This paper develops a Mellin-Laplace analytic framework for the fixed-shift prime correlation r_h(n) = Lambda(n) Lambda(n+h) for h not equal to 0. This sequence has no multiplicati…

Chromopolarizability of charm-beauty quarkonium from $B_{c} (2 S) \to B_{c} π π$ transition

Yun-Hua Chen, Zi-Wei Li

The chromopolarizability of a charm-beauty quarkonium characterizes its interaction with soft gluonic fields and can be probed through heavy quarkonium decays. Using the dispersion…
