Description
BESIII has collected 2.5 billion $\psi(2S)$ events and 10 billion $J/\psi$ events. The huge data
sample provide an excellent chance to search for new physics. We report the search
for the decay $J/\psi\to\gamma + invisible$, which is predicted by next-to-minimal
supersymmetric model. We also report the first search for the invisible decay of
$\Lambda$, which is predicted by the mirror matter model and could explain the
$4\sigma$ discrepancy in neutron lifetime measurement between beam method and bottle
method. A light Higgs $A^0$ is also searched in radiative decay of $J/\psi$
