我们调查的威尔逊流的理论空间中的轨迹。为此目的，我们确定的元胞和矩形项的系数在行动的配置所定义的解决方案的威尔逊流。作为逆蒙特卡罗方法之一的恶魔方法被用来确定它们。从淬火QCD的常规Wilson元格作用量出发，我们发现，作为已知的改进作用量，随着流动的发展，元格系数增大，而矩形元格系数趋于负值。我们还发现，在双耦合理论空间的轨迹形成一条直线。
We investigate a trajectory for the Wilson flow in the theory space. For this purpose, we determine the coefficient of the plaquette and rectangular terms in the action for the configurations defined by the solution of the Wilson flow. The demon method regarded as one of the inverse Monte Carlo methods is used for the determination of them. Starting from the conventional Wilson plaquette action of quenched QCD, we find that the coefficient of the plaquette grows while that of the rectangular tends to negative with the development of the flow as the known improved actions. We also find that the trajectory forms a straight line in the two-coupling theory space.
