Chiral low-energy constants from lattice QCD

Silvia Necco

摘要:

本文综述了利用晶格结果与手征有效理论相匹配计算QCD低能耦合的不同策略。回顾了有效理论的一些预言,总结了首阶(∑,F,Sigma_0,F_0)和次首阶(l_i,L_i)低能常数的研究现状,重点介绍了Nf =2和Nf =2+1晶格模拟的最新结果。

英文摘要:

Different strategies for the computation of QCD low-energy couplings by matching lattice results with the chiral effective theory are reviewed. After recalling some relevant predictions from the effective theory, the current status of leading order (Σ,F, Sigma_0,F_0) and next-to-leading order (l_i, L_i) low-energy constants is summarized, focusing on recent results obtained with N_f=2 and N_f=2+1 lattice simulations.
