寻找来自超对称隐谷的暗光子
Search for dark photons from supersymmetric hidden valleys
摘要：
我们用D0实验寻找一种新的光规范玻色子，即暗光子。在我们考虑的模型中，超对称伙伴是成对产生的，级联成最轻的中性伴子，可以衰变到隐藏的扇区状态加上一个光子或一个暗光子。暗光子通过与光子混合而衰变成费米子对。因此，我们研究了一个以前未探索的最终状态，包含一个光子，两个空间接近的轻子，和大的失踪横向能量。我们没有观察到暗光子的任何证据，并对它们的产生设定了限制。
英文摘要：
We search for a new light gauge boson, a dark photon, with the D0 experiment. In the model we consider, supersymmetric partners are pair produced and cascade to lightest neutralinos that can decay into the hidden sector state plus either a photon or a dark photon. The dark photon decays through its mixing with a photon into fermion pairs. We therefore investigate a previously unexplored final state that contains a photon, two spatially close leptons, and large missing transverse energy. We do not observe any evidence for dark photons and set a limit on their production.
