Search for a light CP-odd Higgs boson in the radiative decays of J/psi

The BESIII Collaboration, M. Ablikim

We search for a light Higgs boson $A^{0}$ in the fully reconstructed decay chain of $J / ψ \to γ A^{0}$ , $A^{0} \to μ^{+} μ^{-}$ using $(225.0 \pm 2.8) \times 1 0^{6}$ $J / ψ$ events colle…

Observation of the Dalitz Decay $η^{'} \to γ e^{+} e^{-}$

M. Ablikim, M. N. Achasov, X. C. Ai +410

We report the first observation of the Dalitz decay $η^{'} \to γ e^{+} e^{-}$ , based on a data sample of 1.31 billion $J / ψ$ events collected with the BESIII detector. The $η^{'}$ mesons are pr…
