| contents | The BESIII experiment is a symmetric e+ e- collider experiment operating at center-of-mass energies from 2.0 to 4.95 GeV. With the world's largest threshold production data set, including 10 billion J/psi events, 2.7 billion psi(3686) events, 7.9 fb^{-1} of D meson pairs from psi(3770) decay, and 7.33 fb^{-1} of D_s D_s^* events between 4.128 and 4.226 GeV, we are able to probe for new physics through precision tests of the Standard Model, searches for exotic low-mass particles, and investigations of forbidden or rare decay processes. In this talk, we report recent studies on Beyond the Standard Model physics conducted by the BESIII collaboration, including searches for axion-like particles, dark photons, QCD axions, and invisible decays of K_S^0. In addition, a series of rare charm decay processes, including searches for lepton and baryon number violation, flavor-changing neutral current processes, and charmonium weak decays, are also investigated to search for new physics at BESIII. |
