论文摘要
我们重新审视了Desplanques，Donoghue和Holstein所拥护的低能量耐药平价违规行为的统一处理，以便在标准模型中低能核过程中对均等违规的均无侵犯的抗衡处理结束。我们使用改进的有效的哈密顿量和对晶格QCD中核子指控的精确的非扰动评估，对奇偶校验的梅森 - 核子耦合常数进行新的评估。与在几种体型核反应中违反Hadronic平价的最新测量值相比，我们发现与这些实验结果的一致性得到了改善，尽管仍然存在一些紧张局势。因此，我们注意到比较核和少数核系统低能常数的更广泛的问题，也考虑到从头开始连接有效的汉密尔顿方法来进行手性有效理论的有效的哈密顿式方法时也无法解决的理论问题。我们注意到，未来的实验和晶格QCD研究如何使新兴的情况提升，从而促进了对````端到端'''''端到端'''理论描述的实验室的研究。
We revisit the unified treatment of low-energy hadronic parity violation espoused by Desplanques, Donoghue, and Holstein to the end of an ab initio treatment of parity violation in low-energy nuclear processes within the Standard Model. We use our improved effective Hamiltonian and precise non-perturbative assessments of the quark charges of the nucleon within lattice QCD to make new assessments of the parity-violating meson-nucleon coupling constants. Comparing with recent, precise measurements of hadronic parity violation in few-body nuclear reactions, we find improved agreement with these experimental results, though some tensions remain. We thus note the broader problem of comparing low-energy constants from nuclear and few-nucleon systems, considering, too, unresolved theoretical issues in connecting an ab initio, effective Hamiltonian approach to chiral effective theories. We note how future experiments and lattice QCD studies could sharpen the emerging picture, promoting the study of hadronic parity violation as a laboratory for testing ``end-to-end'' theoretical descriptions of weak processes in hadrons and nuclei at low energies.
