英文摘要	Using 58 million J/psi decays obtained by BESII, a charged kappa particle is observed in the analysis of the K-S pi(+/-) system recoiling against K*(892)(-/+) selected in J/psi -> KSKS pi(+)pi(-). The mass and width values of the charged kappa are obtained to be (826 +/- 49(-34)(+49)) MeV/c(2) and (449 +/- 156(-81)(+144)) MeV/c(2) for the Breit-Wigner parameters, and the pole position is determined to be (764 +/- 63(-54)(+71)) - i(306 +/- 149(-85)(+143)) MeV/c(2). They are in good agreement with those of the neutral K observed by the BES Collaboration. (C) 2011 Elsevier B.V. All rights reserved.
