类空区严格π介子电磁形状因子行为

Rigorous pion electromagnetic form factor behavior in the space-like region

M. Belicka, S. Dubnicka, A. Z. Dubnickova, A. Liptaj

摘要:

利用解析性,将$σ_{tot}(e^+e^- \to π^+ π^-)$的新的精确实验信息转移到类空区域。结果得到严格的π介子电磁形状因子行为。后者与一些现有的模型预测进行了比较。

英文摘要:

New precise experimental information on $σ_{tot}(e^+e^- \to π^+ π^-)$ is transferred into the space-like region, by taking advantage of the analyticity. As a result a rigorous pion electromagnetic form factor behavior is obtained. The latter with some existing model predictions is compared.
