摘要

路径优化是针对有限密度QCD等场论中出现的符号问题而提出的。该方法通过优化复杂平原上的积分路径来提高平均相位因子。在本研究中，我们讨论了作为有限密度QCD的第一步，该方法在低维QCD中的应用。

The path optimization for the sign problem of low dimensional QCD

The path optimization has been proposed to weaken the sign problem which appears in some field theories such as finite density QCD. In this method, we optimize the integration path in complex plain to enhance the average phase factor. In this study, we discuss the application of this method to low dimensional QCD as a first step of finite density QCD.
