Description
We perform Dalitz plot analyses of $J/\psi$ three-body hadronic decays to $\pi^+ \pi^-\pi^0$, $K^+ K^-\pi^0$ and $K^0_S K^{\pm} \pi^{\mp}$ using the isobar and Veneziano models. The $J/\psi$ is produced through the Inital-State-Radiation process. We also perform Dalitz plot analyses of $\eta_c$ three-body hadronic decays to $K^+ K^-\pi^0$ and $K^0_S K^{\pm} \pi^{\mp}$, where the $\eta_c$ is produced in two-photon interactions. We study the $\Upsilon(1S)$ radiative decays to $\gamma \pi^+ \pi^-$ and $\gamma K^+ K^-$ using data recorded at center-of-mass energies at the $\Upsilon(2S)$ and $\Upsilon(3S)$ resonances. Branching fraction measurements and spin-parity analyses are reported for all the resonances observed in the mass spectra.
