小希格斯模型为SM的{\it层次问题}提供了一种新的解决方法。这一问题与SM尺度与板材尺度差异较大有关。这些模型的主要特征之一是存在像顶夸克这样的矢量。SM模型的CP违背$K_L \to \pi^0 \nu \bar{\nu}$过程以顶夸克企鹅图和盒图为主。我们在小希格斯模型中检验这一过程，其中顶夸克扇区与标准模型有显著差异。
Little Higgs models provides us a new solution of the {\it hierarchy problem} of the SM. The problem is associated with the large difference in scales of SM and plank scale. One of the main features of these models is the existence of a vector like top quark. The CP violating $K_L \to \pi^0 \nu \bar{\nu}$ process n the SM model is dominated by top quark penguin & box graphs. We examine this process in the Little Higgs model where the top quark sector has significant differences from the Standard Model.
