重子手性微扰理论（BChPT）作为低能量子色动力学（QCD）的一种有效的场理论，对我们理解非微扰强相互作用现象已经并将继续发挥重要作用。在过去的二十年里，受晶格QCD模拟的快速发展和低能QCD奇异区研究的新实验活动的启发，人们做出了许多努力来开发一个全协变BChPT并测试其在所有情况下的有效性。这些新的努力不仅加深了我们对一些长期存在的问题的理解，如幂次计数破断问题和收敛问题，而且还产生了可以自信地应用于做出稳健预测的理论工具。特别是，明显协变的BChPT与质量壳上扩展（EOMS）重整化方案相比，满足所有解析性和对称性约束，收敛速度相对更快。在本文中，我们简要介绍了全协变BChPT及其在u、d、s三味领域的最新应用。
Baryon chiral perturbation theory (BChPT), as an effective field theory of low-energy quantum chromodynamics (QCD), has played and is still playing an important role in our understanding of non-perturbative strong-interaction phenomena. In the past two decades, inspired by the rapid progress in lattice QCD simulations and the new experimental campaign to study the strangeness sector of low-energy QCD, many efforts have been made to develop a fully covariant BChPT and to test its validity in all scenarios. These new endeavours have not only deepened our understanding of some long-standing problems, such as the power-counting-breaking problem and the convergence problem, but also resulted in theoretical tools that can be confidently applied to make robust predictions. Particularly, the manifestly covariant BChPT supplemented with the extended-on-mass-shell (EOMS) renormalization scheme has been shown to satisfy all analyticity and symmetry constraints and converge relatively faster compared to its non-relativistic and infrared counterparts. In this article, we provide a brief review of the fully covariant BChPT and its latest applications in the u, d, and s three-flavor sector.
