AI 中文摘要
在低能弱相互作用过程中寻找超越标准模型的新物理,需要在树级和圈级水平上精确了解标准模型背景。在许多此类情况下,由于核子或原子核的非微扰结构,辐射修正是理论不确定性的主要来源之一。在这篇综述中,我讨论了基于色散关系、格点规范理论和核多体计算的几种现代策略,以确定低能弱相互作用过程(如β衰变和宇称破坏的电子-原子核散射)中辐射修正的强子及核不确定性。
英文摘要
The search for physics beyond the Standard Model in low-energy weak interaction processes requires a precise knowledge of the Standard Model background at tree- and loop-level. In many such cases, radiative corrections represent one of the major sources of theory uncertainty due to the non-perturbative structures of nucleon or nuclei. In this review, I discuss several modern strategies based on dispersion relation, lattice gauge theory and nuclear many-body calculations to pin down the hadronic and nuclear uncertainties in the radiative corrections to low-energy weak interaction processes such as beta decays and parity-violating electron-nucleus scattering.
