Description
The recent results of the partial-wave analysis of $J/\psi \to K^+K^-\pi^0$ reaction using $(223.7\pm1.4)\times 10^{6}$ $J/\psi$ decays collected by BESIII Collaboration in 2009 will be presented. The high data quality and unprecedented statistics of the BESIII experiment allowed revealing signals that had not been observed previously in $J/\psi$ decays. The reported results for $K^*(892)^\pm$ and $K^*_2(1430)^\pm$ parameters are currently the most precise. The $K^*_2(1980)^\pm$ and $K^*_4(2045)^\pm$ resonances are observed for the first time in $J/\psi$ decays. Two resonance signals in the $K^+K^-$ channel are also reported and their interpretation will be discussed. Results also include branching fractions for decays through intermediate states and a high precision measurement of $B(J/\psi \to K^+K^-\pi^0)$. The results of the partial-wave analysis differ significantly from those previously obtained by BESII and BABAR.
