27 Sep 2001 | | Journal: | Eur.Phys.J.direct C4 (2002) 4 | | Subject: | hep-ph | | Affiliation: | Cracow IFJ | | Abstract: | We use our former results on pi+pi- S-wave obtained in a nearly assumption-free way from the 17.2 GeV/c data to predict the pi0pi0 S--wave. The predictions are compared with the recent results of the E852 experiment at 18.3 GeV/c. A good agreement is found for only one (the "down-flat") solution while the second one (the "up-flat") is excluded by the pi0pi0 data. Thus the long-standing "up-down" ambiguity has been finally resolved in favour of the S-wave intensity which stays large and nearly constant up to the KK-bar threshold. A joint analysis of both sets of data leads to a reduction of errors for this solution. | | Source: | arXiv, hep-ph/0109268 | | Services: | Forum | Review | PDF | Favorites | |
