| contents | Dark matter (DM) is a new type of invisible matter introduced to explain various features of recent astrophysical observations, including galaxy rotation curves and other fundamental characteristics of our universe. DM may couple to ordinary matter via portals, which open up possibilities for new particles, such as axion-like particle, light Higgs boson, dark photon, and spin-1/2 fermions. If the masses of these particles lie in the MeV to GeV range, they can be explored by high-intensity electron-positron collider experiments, such as the BESIII experiment. BESIII has accumulated a huge amount of datasets at several energy points, including the $J/ψ$, $ψ(3686)$, and $ψ(3770)$ resonances. BESIII has recently explored the possibility for axion-like particle and light Higgs boson through radiative $J/ψ$ decays, dark photon via the initial-state radiation process, and a massless dark photon in $Λ_c$ decays. This report highlights the latest results from the BESIII experiment on these topics. |
