论文摘要
我们建议在第四代存储环Sirius的Sirius遗址的巴西同步灯实验室首次搜索黑暗区域。我们表明，Sirius的前任UVX可以成为具有前所未有的灵敏度的有前途的黑暗扇区探测器。该搜索基于1-3 GEV正电子光束撞击厚目标，导致$ e^+ e^ - \rightArrowγA'$反应，然后进行缺失的质谱事件重建。我们表明，SEDs有可能在数据的几个月内探测质量高达55 MeV的质量和动力学耦合到$ε\ SIM \ SIM \ SIM \ SIM \ SIM \ SIM \ SIM \ SIM \ sim \ Sim \ Sim \ Sim。因此，此类实验将构成10-55 MEV质量范围的全球最佳深色光子探针，能够探测一个未开发的参数空间区域。
We propose the first Search for Dark Sector at the Brazilian Synchrotron Light Laboratory, site of Sirius, a fourth-generation storage ring. We show that UVX, Sirius predecessor, can be a promising dark sector detector, SeDS, with unprecedented sensitivity. The search is based on a 1-3 GeV positron beam impinging on a thick target leading the $e^+ e^- \rightarrow γA'$ reaction, followed by a missing mass spectrum event reconstruction. We show that SeDS has the potential to probe dark photons with masses up to 55 MeV and kinetic coupling down to $ε\sim 10^{-14}$ within months of data. Therefore, such experiment would constitute the best dark photon probe worldwide in the 10-55 MeV mass range, being able to probe an unexplored region of parameter space.
