DESCRIPTION:Speakers: Igor Denisenko (JINR)\nThe recent results of the par
 tial wave analysis of $J/\\psi \\to\nK^+K^-\\pi^0$ 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 statistics of the BES
 III experiment allowed revealing signals that had not been observed previo
 usly in $J/\\psi$ decays. The reported results for $K^*(892)^\\pm$ and $K^
 *_2(1430)^\\pm$ parameters are currently the most precise. The $K^*_2(1980
 )^\\pm$\, $K^*_4(2045)^\\pm$ resonances are reported for the first time in
  $J/\\psi$ decays. Two resonance signals in the $K^+K^-$ channel are repor
 ted and their interpretation will be discussed. Results also include branc
 hing ratios for decays through these intermediate states and a high precis
 ion measurement of $Br(J/\\psi \\to K^+K^-\\pi^0)$. The results are signif
 icantly different from those presented earlier by BESII and BABAR.\n\nhttp
