闵可夫斯基时空中的重整化

Renormalization in Minkowski space-time

I. Steib, S. Nagy, J. Polonyi

摘要:

本文将乘法和泛函重整化群方法应用于四维Minkowski时空中的标量理论。有人认为,适当选择的减法点是更重要的闵可夫斯基比在欧氏时空。截断理论的参数,定义在准粒子域中的一个减法点,是复杂的,由于质量壳贡献和重整化群流变得比它的欧几里德对应。

英文摘要:

The multiplicative and the functional renormalization group methods are applied for the four dimensional scalar theory in Minkowski space-time. It is argued that the appropriate choice of the subtraction point is more important in Minkowski than in Euclidean space-time. The parameters of the cutoff theory, defined by a subtraction point in the quasi-particle domain, are complex due to the mass-shell contributions and the renormalization group flow becomes much more involved than its Euclidean counterpart.
