Investigating Dark Matter in Semi-Visible Jets at CERN

暗物质是我们目前对宇宙认识中的主要谜团之一，它的性质是完全未知的。暗物质可以由粒子组成，也可以在大型强子对撞机碰撞中产生。这个项目的重点是类QCD暗扇区的模型，它将在大型强子对撞机的碰撞中产生非传统的信号。在某些情况下，暗粒子一旦在碰撞中产生，就会立即衰变，这些暗粒子是由较浅的暗(不可见)粒子和产生半可见喷流的SM粒子组成的。

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.
