有效场论中的强子宇称破缺

Hadronic parity violation in effective field theory

M. R. Schindler

摘要:

本文叙述了有效场论在两核子和三核子系统中强子宇称破缺的应用。这些方法提供了几个重要的优势,传统上使用的介子交换模型,例如,模型独立性和可靠估计理论误差的可能性。我们专注于所谓的“无π介子”理论,并描述了各种两个和三个核子观测的计算。宇称破坏的三核子相互作用的作用进行了讨论。

英文摘要:

The application of effective field theories to hadronic parity violation in two- and three-nucleon systems is described. These methods provide several important advantages over the traditionally used meson-exchange models, e.g., model independence and the possibility to reliably estimate theoretical errors. We focus on the so-called "pionless" theory and describe calculations of various two- and three-nucleon observables. The role of parity-violating three-nucleon interactions is also discussed.
