Investigating Dark Matter in Semi-Visible Jets at CERN

暗物质代表了我们目前对宇宙的理解中的主要谜团之一，它的性质完全未知。暗物质可以由粒子组成，并可以在大型强子对撞机碰撞中产生。该项目的重点是类似QCD的暗区模型，该模型将在LHC碰撞中产生非常规签名。在某些情况下，暗粒子一旦在碰撞中以较亮的暗（不可见）粒子和SM粒子的混合物产生就会衰变，从而产生半可见的喷流。

Dark matter represents one of the main mysteries in our current understanding of the universe and its nature is completely unknown. Dark matter could be made of particles and could be generated in the Large Hadron Collider collisions. This project focuses on models of a QCD-like dark sector which would generate unconventional signatures in LHC collisions. In some cases, the dark particles can decay as soon as they are produced in the collisions in a mixture of lighter dark (invisible) particles and SM particles generating semi-visible jets.
