标准模型及其以后的次主导阶强子修正
Next-to-the-Leading-Order Hadronic Corrections for Standard Model and Beyond
摘要：
我们探讨各种扩展的计算包，如Feynarts和FormCalc在应用程序中的电子-质子散射的不对称性相关的G 0和QWeak实验的计算。我们的计算在强子顶点使用偶极子形状因子完成到次主导阶（单圈）。在Q^2 = 0.1 ~ 1.0 GeV^2的范围内，我们没有发现双极型和偶极型不对称性之间的显著差异。我们的结果与G 0合作组的理论预测吻合得很好，但与实验结果有出入。这种与实验结果的差异是由于质子的奇怪内容以及可能的新物理学。
英文摘要：
We explore various extensions of computational packages such as Feynarts and FormCalc in application to calculation of the electron-proton scattering asymmetries relevant to the G0 and QWeak experiments. Our calculations where completed up to the Next-to-the-Leading-Order (one-loop) using the dipole form factor in hadronic vertices. We saw no significant difference between monopole and dipole type of asymmetry over the range of Q^2 = 0.1 - 1.0 GeV^2. Our results are in the good agreement with theoretical predictions by the G0 collaboration, but show discrepancy from the experiment. This discrepancy from the experimental results is due to the strange content of the proton and possibly new physics as well.
