摘　　要：小Higgs模型是高能物理的研究热点之一,但是,最初的小Higgs模型却与弱电精确测量存在着矛盾,因此,人们引入了T宇称。T宇称要求近似守恒或者有着非常小的破缺。这里利用宇宙学观测量对Littest Higgs模型中的T宇称破缺参数进行了严格的限制。Little Higgs model is one of the hot spots in high-energy physics, but the initial little Higgs model contradicted the accurate measurement of electroweak theory, so T-parity was introduced to solve the problem. The T- parity was required to be conserved or it could have a very small breaking. Cosmological observables was introduced to restrict the breaking parameters of littlest Higgs model with T-parity in the paper.
