Abstract
Identifying the nature of dark matter is an unsolved problem in astronomy and particle physics. Although a lot of evidence is observed in astronomical experiments, there is no evidence from collider experiments. Many theories beyond the Standard Model predict light dark matter, dark photon and dark gauge boson, which may be light enough for BESIII to observe. BESIII has recently searched for invisible decays of light mesons and dark photons as well as dark gauge bosons using the 1.3 billion J/ψ data sample. This poster summaries the recent results from BESIII collaboration on these dark sector topics.
