The left-right symmetric models extend the gauge group of the Standard Model enabling treatment of the left- and right-handed fermions in the same footing. The left-right symmetry requires the existence of right-handed neutrinos, leading naturally to non-zero masses for neutrinos. Here some aspects of a supersymmetric version of the left-right symmetric models are reviewed. Such models have many virtues, including possibility for dark matter without any new additional symmetry needed in order to have a stable lightest supersymmetric particle. In the model the lightest sneutrino or the lightest neutralino can form dark matter of the universe, at the same time fulfilling all the experimental constraints. The dark matter particle in the model can be very different from the dark matter typical in the minimal supersymmetric standard model. Specific signals for this kind of models at the LHC are also discussed.

LHC的最小超对称左右模型,暗物质和信号

左右对称模型扩展了标准模型的量规组,从而可以在同一基础上处理左手和右手费米子。左右对称需要右手中微子的存在,自然导致中微子的质量为非零。这里回顾了左右对称模型的超对称版本的某些方面。这种模型具有许多优点,包括暗物质的可能性,而无需任何新的额外对称性即可拥有一个最稳定的最轻的超对称粒子。在模型中,最轻的中微子或最轻的中性子可以形成宇宙的暗物质,同时满足所有实验约束。模型中的暗物质粒子可能与最小超对称标准模型中的典型暗物质有很大不同。
