手征有效场论中离散时空对称性的破坏

Violations of discrete space-time symmetries in chiral effective field theory

J. de Vries, Ulf-G. Meißner

摘要:

本文综述了强子和核系统中离散时空对称性破坏的理论描述的最新进展。我们重点讨论了标准模型弱相互作用引起的宇称破坏和时间反演守恒相互作用,以及非零QCD θ项或超越标准模型物理引起的宇称破坏和时间反演破坏相互作用。我们讨论了这种相互作用的起源,并回顾了手征有效场论扩展的发展,包括离散对称性破坏。本文讨论了多体破坏手征拉格朗日量和核子-核子势的构造及其在少体系统中的应用。

英文摘要:

We review recent progress in the theoretical description of the violation of discrete space-time symmetries in hadronic and nuclear systems. We focus on parity-violating and time-reversal-conserving interactions which are induced by the Standard Model weak interaction, and on parity- and time-reversal-violating interactions which can be caused by a nonzero QCD theta term or by beyond-the-Standard Model physics. We discuss the origins of such interactions and review the development of the chiral effective field theory extension that includes discrete symmetry violations. We discuss the construction of symmetry-violating chiral Lagrangians and nucleon-nucleon potentials and their applications in few-body systems.
