摘要:

我们给出了动量转移范围Q^2=4-40 GeV^2的γ-γ * -> π 0跃迁形状因子和动量转移范围Q^2=2-50 GeV^2的γ-γ * -> eta_c跃迁形状因子的测量结果。文中还给出了eta_c质量、总宽度和双光子宽度的测量结果。

英文摘要:

We present measurements of the gamma gamma* --> pi0 transition form factor for the momentum transfer range Q^2=4-40 GeV^2 and the gamma gamma* --> eta_c transition form factor for the range Q^2=2-50 GeV^2. The results of the measurement of the eta_c mass, total and two-photon widths are also presented.
