计算了T宇称最小Higgs模型（LHT）中e（+）e（-）->gamma gamma -> bb过程的截面.我们发现，在有利的参数下，总截面σ（e（+）e（-）->gamma gamma -> bb）对破缺标度f、混合参数x（L）、镜夸克质量m（Hi）敏感，LHT模型的相对修正为百分之几到百分之几十。该截面明显大于标准模型和其他典型新物理模型的相应结果。因此，在LHT模型中的预测是相当不同的其他新的物理模型的预测，这样一个过程是真正有趣的寻找LHT模型的迹象。
We have calculated the cross section of the process e(+)e(-)->gamma gamma -> bb in the littlest Higgs model with T parity (LHT). We find that, for the favorable parameters, the total cross section sigma(e(+)e(-)->gamma gamma -> bb) is sensitive to the breaking scale f, mixing parameter x(L), the masses of the mirror quarks m(Hi), and the relative correction of the LHT model is a few percent to dozens of percent. The cross section is significantly larger than the corresponding results in the standard model and in the other typical new physics models. Therefore the prediction in the LHT model is quite different from the predictions in other new physics models and such a process is really interesting in searching for the signs of the LHT model.
