Abstract
Using a sample of 1.3 billion J= events collected with the BESIII detector at the BEPCII storage ring, the decay channel J= ! ! 0 0 has been studied. Two of the lightest tetraquark candidates, f0(500) (a.k.a. ) and f0(980) have been searched for. A Dalitz Plot analysis has been performed and in additon to f0(500) ( ) and f0(980), f2(1270), b1(1325), (1450), and f2(2300) have been observed. The analysis and background study indicate that this channel is suitable for a detailed study of the resonances through a Partial Wave Analysis.
