| Description: |
A partial-wave analysis is performed on the decay /→000 within the 000 invariant-mass region below 1.6 GeV/2, using (10.09±0.04)×109 / events collected with the BESIII detector. Significant isospin-violating decays of (1405) and 1(1420) into 0(980)0 are observed. For the first time, three axial vectors, 1(1285), 1(1420), and 1(1510), are observed to decay into 000. The product branching fractions of these resonances are reported. |
