论文摘要
自从量子场理论首先应用于20世纪中叶的核力量推导以来，与现实耦合的pion交换的重新归一化已经提出了挑战。在1990年代实施有效的现场理论（EFT），答应了解决这个问题的解决方案，但遇到了意外的障碍。核能社区的反应是将重点放在“手性潜力”上，并被选为对数据进行良好描述的监管机构。同时，在没有明确的pion交换的情况下成功的EFT - - 无钢丝EFT - - 在系统扩展中，在低能核可观察物的系统扩张中通过顺序实现了重新归一化的情况。我描述了如何将无疑EFT的教训应用于正确重新归一化的手性EFT的构建。
Ever since quantum field theory was first applied to the derivation of nuclear forces in the mid-20th century, the renormalization of pion exchange with realistic couplings has presented a challenge. The implementation of effective field theories (EFTs) in the 1990s promised a solution to this problem but unexpected obstacles were encountered. The response of the nuclear community has been to focus on "chiral potentials" with regulators chosen to produce a good description of data. Meanwhile, a successful EFT without explicit pion exchange --- Pionless EFT --- has been formulated where renormalization is achieved order by order in a systematic expansion of low-energy nuclear observables. I describe how lessons from Pionless EFT are being applied to the construction of a properly renormalized Chiral EFT.
