~ 3 He上μ子俘获的核子弱结构

The weak structure of the nucleon from muon capture on 3He

Doron Gazit

摘要:

本文通过对弱俘获过程~ 3 He(μ^{-},ν_μ)~ 3 H的微观计算,提取和约束了核子的弱形状因子,特别是感生赝标和第二类流。诱导的赝标形状因子与手征微扰理论的预测一致。矢量流守恒(CVC)假设的约束是迄今为止最严格的。

英文摘要:

I use a microscopic calculation of the weak capture process 3He(μ^{-},ν_μ)3H, to extract and constrain the weak form factors of the nucleon, particularly the induced pseudo-scalar, and the second-class currents. The induced pseudo-scalar form-factor is found to agree with the prediction of chiral perturbation theory. The constraint found on the conservation of vector current (CVC) hypothesis is the tightest to date.
