KLOE/KLOE-2强子截面的测量

Measurement of hadronic cross section at KLOE/KLOE-2

Veronica De Leo

摘要:

$σ(e^+e^-\rightarrow π^+π^-)$截面的测量允许确定π介子形状因子$| F_π|^2$和两个π介子对μ子异常$a_μ$的贡献。已在弗拉斯卡蒂$ϕ$工厂的$DAΦNE$使用KLOE检测器进行了此类测量。将最后一次分析(KLOE 12)与之前两次发表的分析(KLOE 08、KLOE 10)结合的初步结果将在下文中给出。

英文摘要:

The measurement of the $σ(e^+e^-\rightarrow π^+π^-)$ cross section allows to determine the pion form factor $| F_π|^2$ and the two pion contribution to the muon anomaly $a_μ$. Such a measurement has been performed with the KLOE detector at $DAΦNE$, the Frascati $ϕ$-factory.The preliminary results on the combination of the last analysis (KLOE12) with two previous published (KLOE08, KLOE10) will be presented in the following.
