| 英文摘要 | Based on a sample of 1.31 x 10(9) j/psi events collected with the besiii detector at the bepcii collider, dalitz plot analyses of selected 79,625 eta -> pi(+)pi(-)pi(0) events, 33,908 eta -> pi(0)pi(0)pi(0) events, and 1,888 eta' -> pi(0)pi(0)pi(0) events are performed. the measured matrix elements of eta -> pi(+)pi(-)pi(0) are in reasonable agreement with previous measurements. the dalitz plot slope parameters of eta -> pi(0)pi(0)pi(0) and eta' -> pi(0)pi(0)pi(0) are determined to be -0.055 +/- 0.014 +/- 0.004 and -0.640 +/- 0.046 +/- 0.047, respectively, where the first uncertainties are statistical and the second systematic. both values are consistent with previous measurements, while the precision of the latter one is improved by a factor of 3. final state interactions are found to have an important role in those decays. |
