Search for an axion-like particle in radiative $J / ψ$ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +588

We search for an axion-like particle (ALP) $a$ through the process $ψ (3686) \to π^{+} π^{-} J / ψ$ , $J / ψ \to γ a$ , $a \to γ γ$ in a data sample of $(2.71 \pm 0.01) \times 1 0^{9}$ …

Impact of the interference between the resonance and continuum amplitudes on vector quarkonia decay branching fraction measurements

Y. P. Guo, C. Z. Yuan

The measurement of the branching fraction of a heavy quarkonium decaying into light hadronic final state at $e^{+} e^{-}$ colliders is revisited. In $e^{+} e^{-}$ annihilation experiments, b…
