Abstract:

In the 1930s,astronomical observations presented severe challenges to the standard universe model.

In order to reconcile the contradiction between observational data and theoretical models,theoretical physicists proposed dark matter theory. Since then,experimental physicists have explored various dark matter detection schemes.

This paper introduces the origin of dark matter concept,the basic properties of dark matter,the principle and method of dark matter detection and the latest progress of DAMPE in detecting dark matter. The focus is on DAMPE data,with electronic spectrum analysis as the core,before based on human research,the multilevel and multidirectional synthesis of DAMPE data and results further elaborates the profound significance of Tev inflection and sharp signal in DAMPE electronic spectrum. Finally,relying on some information obtained during the research process,put forward some opinions and insights on future dark matter detection experiments.

Key words: dark matter, cosmic ray electron spectrum, indirect detection, high altitude detection, DAMPE
