Overview of high energy physics and prospective dark matter detections at HL-LHC and CEPC

Abstract

This paper first takes an overview of the current development of high-energy physics, including an introduction to the fundamental particles and forces described by the standard model, physics beyond the standard model like super-symmetry and matter-antimatter asymmetry, and current high-energy physics experiments such as ATLAS and CMS at the large hadron collider. Then we focus on the prospective dark matter detections at the high-luminosity large hadron collider (HL-LHC) and circular electron-positron collider (CEPC), especially the upgrades of the current LHC and different working modes of the CEPC. Finally, the paper discusses the prospects of dark matter detection and possibly dark matter candidates.
