Dark photon search status in energy region
Zhijun Li, Zhengyun You
The dark photon plays an important role as a portal to dark matter and has been extensively studied on both experimental and theoretical frontiers. However, as no signals have been…
Observation of the decay at BESIII
Zhijun Li, Zhengyun You
In the decays of and , there are discrepancies between the theoretical calculations and the PDG experimental values, referred to as the charmonium QCD puzzle…
Search for dark sector at BESIII
Zhijun Li, Zhengyun You
BESIII experiment has collected a large data sample of charmonium, charm mesons, hyperons, and other light mesons. These data provide a unique opportunity to explore the dark secto…
Dark sector search at BESIII
Zhijun Li, Zhengyun You
The Standard Model has achieved significant success in particle physics; however, there are still some unresolved puzzles beyond it. This motivates the exploration of the dark sect…
Search for exotic physics at BESIII
Zhijun Li, Zhengyun You
Exotic physics typically encompasses two categories of exotic particles: ``dark" particles beyond the standard model and exotic hadrons within the extended standard model. We prese…
Rare Charm Decays at BESIII
Zhijun Li, Zhengyun You
The rare and forbidden processes within the Standard Model offer an opportunity to explore potential new physics beyond the SM. We summarize the research method and the recent resu…
