摘要：
We have measured the three form factors governing the decay D+ ->K over-bar *0e+ve observed in Fermilah photoproduction experiment E691, using the complete decay distribution of the data. The results are A1 (0) =0.46 ±0.05 ±0.05, A2(0) =0.0 ±0.2 ±_0.1, and v(0) =0.9 ±0.3 ±0.1 for the two axial-vector and the vector form factors, respectively. The K over-bar *0 mesons have a ratio of longitudinal to transverse polarization of 1.8-0.4+0.6 ±0.3. These results are significantly different from values predicted by a number of different models.
