英文摘要	The BES data on the J/psi -> eta K(0)(K) over bar(0) reaction show a clear enhancement in the K(0)(K) over bar(0) mass distribution close to the threshold of this channel. Such an enhancement is usually a signature of an L = 0 resonance around threshold, which in this case would correspond to an h1 state with quantum numbers I-G(J(Pc))= 0(-)(1(+-)). A state around 1800 MeV results from the interaction of the KTC using the local hidden gauge approach. We show that the peak observed in J/psi -> eta K(0)(K) over bar(0) naturally comes from the creation of this h(1) state with mass and width around 1830 MeV and 110 MeV, respectively. A second analysis, model independent, corroborates the first result, confirming the relationship of the enhancement in the invariant mass spectrum with the h(1) resonance. (C) 2013 The Authors.
