标题： Nucleon Polarizabilities: Theory

摘要： 我们回顾了对核子极化率理论研究的最新进展。 我们首先报告了在真实康普顿散射中测量的静态极化率，比较并解释了各种理论方法的结果。 在第二步中，我们将讨论扩展到可以在虚拟康普顿散射中获取的广义极化率，说明这些量中编码的信息如何提供对核子中感应极化密度的空间解释。 显示英文摘要

摘要： We review recent developments in the theoretical investigation of the nucleon polarizabilities. We first report on the static polarizabilities as measured in real Compton scattering, comparing and interpreting the results from various theoretical approaches. In a second step, we extend the discussion to the generalized polarizabilities which can be accessed in virtual Compton scattering, showing how the information encoded in these quantities can provide a spatial interpretation of the induced polarization densities in the nucleon.
