我们考虑一类小希格斯理论与$T$-宇称，所有新的粒子负责取消标准模型的贡献，在希格斯势的单圈二次发散是奇数下的$T$-宇称，包括重顶部的合作伙伴，这是以前采取的$T$-偶。新的结构大大简化了顶级部门的频谱，并完全改变了顶级合作伙伴的现象。在强子对撞机的信号这类$T $不变的模型似乎更类似于超对称。我们开始研究对撞机的现象学，并讨论了区分这类模型的挑战，从超对称性在大型强子对撞机。
We consider a class of little Higgs theories with $T$-parity where all new particles responsible for canceling the standard model contributions to the one-loop quadratic divergences in the Higgs potential are odd under $T$-parity, including the heavy top partner which was previously taken to be $T$-even. The new construction significantly simplifies the spectrum in the top sector and completely changes the phenomenology of the top partner. At hadron colliders the signals of this class of $T$-invariant models appear to be even more similar to supersymmetry. We initiate a study on the collider phenomenology and discuss the challenge of distinguishing this class of models from supersymmetry at the Large Hadron Collider.
