| contents | This report highlights the recent BESIII results related to the new physics searches motivated by the shortcomings of Standard Model, such as the exclusion of dark matter (DM). DM has so far been inferred only through astrophysical observations and accounts for a large fraction of matter density of the universe. DM may couple to SM particles via various portals. These portals give rise to several possible new particles beyond the SM, such as light Higgs bosons, dark photons, axion-like particles, or spin-1/2 fermions. Furthermore, the origin of DM and the observed asymmetry between visible matter and antimatter may be connected through the introduction of a dark baryon. The signature of these new physics particles could be accessible by the BESIII if their masses lie in the few-GeV range. |
