Title: 赝标介子跃迁形式因子

Abstract: Present-day experimental and phenomenological situation about pseudoscalar ($\pi^0$, $\eta$, $\eta'$) meson transition form factors is briefly reviewed. Necessity of more sophisticated behaviours in time-like region of these form factors is emphasized. Four-resonance unitary and analytic model of the pseudoscalar meson transition form factors is constructed, which describes well all existing experimental information. Show Chinese abstract

Abstract: 现有关于赝标介子($\pi^0$, $\eta$, $\eta'$)介子转变形式因子的实验和现象学情况被简要回顾。强调了这些形式因子在类时区域需要更复杂的特性。构建了一个四共振的单位性和解析模型，用于赝标介子转变形式因子，该模型能很好地描述所有现有的实验信息。
