摘要：
We point out some properties of the amplitude of the dipion transition Upsilon(3S)->Upsilon(1S)pi pi in relation to the recently reported results of a CLEO analysis of form factors in this amplitude. We find that the reported significant complex phase between two of the form factors, under the assumption that the third form factor is zero, is not consistent with the picture where the phase shifts arise due to the final state interaction in the pi pi channel. It is also shown that in an analysis that uses no information on the polarization of both the initial and the final Upsilon resonances it is impossible in principle to determine all the relevant terms. We suggest that a study of a simple correlation between the direction of the total momentum of the two pions and the axis of the initial beams is sufficient to resolve the ambiguity in the fit for the form factors.
