| 英文摘要 | We perform a model-independent analysis for recently reported data of the pi(+)pi(-) invariant mass spectra in the gamma (4S) -> gamma (1S, 2S)pi(+)pi(-) decays and point out that there does exist a broad peak below 0.6 GeV in the data of the gamma(4S) -> gamma(1S)pi(+)pi(-) decay, which is analogous to that in the gamma (3S) -> gamma(1S)pi(+)pi(-) decay. With the data of gamma(4S) decays, we further test our model developed for studying the puzzle in the gamma (3S) -> gamma (1S) pi(+)pi(-) decay. The result shows that with such a model, all the pi(+)pi(-) invariant mass spectra of gamma (4S) decays can be described. We also predict the cos theta(pi)* distributions of gamma (4S) -> gamma (1S, 2S)pi(+)pi(-) decays, which can be used to justify our model prediction. (c) 2007 Elsevier B.V. All rights reserved. |
