我们将QCD中用于估计手征拉格朗日算子强度的“朴素维数分析”参数推广到强耦合超对称理论。特别是,我们展示了如何计算4π的因子--这是一门不精确的科学,但当这些理论被用来模拟真实的粒子物理学时,却是一门有用的艺术。
We extend the “naïve dimensional analysis” arguments used in QCD for estimating the strengths of operators in chiral Lagrangians to strongly coupled supersymmetric theories. In particular, we show how to count factors of 4π — an inexact science, but nevertheless a useful art when such theories are used to model real particle physics.
