重子手征微扰理论中核子的极化率

Polarisabilities of the nucleon in baryon chiral perturbation theory and beyond

Vadim Lensky, Vladimir Pascalutsa

摘要:

我们回顾了最近重子手征微扰理论对核子极化率的研究结果,这些结果描述了核子康普顿散射的不同区域-实的、虚的和双虚的。我们强调的非弹性核子结构的修正,如双光子交换贡献的计算的背景下,该理论的经验验证的重要性。我们还讨论了最近获得的约束,涉及不同的制度的核子康普顿散射,并可以提供更多的信息核子结构。

英文摘要:

We review the recent baryon chiral perturbation theory results for the nucleon polarisabilities that describe the different regimes of nucleon Compton scattering --- real, virtual, and doubly virtual. We stress the importance of the empirical verification of the theory in the context of the calculation of the inelastic nucleon structure corrections, such as the two-photon exchange contributions. We also discuss the recently obtained constraints that relate the different regimes of nucleon Compton scattering and can provide additional information on the nucleon structure.
