Observation of $ψ (3770) \to η J / ψ$

BESIII Collaboration

The Born cross section of the process $e^{+} e^{-} \to η J / ψ$ at a center-of-mass energy $s = 3.773 GeV$ is measured to be ( $8.89 \pm 0.88 \pm 0.42$ ) $pb$ , using a data…

Search for the decay $η^{'} \to γ γ η$

M. Ablikim, M. N. Achasov, P. Adlarson +479

Using a data sample of $1.31 \times 1 0^{9} J / ψ$ events collected with the BESIII detector, a search for $η^{'} \to γ γ η$ via $J / ψ \to γ η^{'}$ is performed for the first time. No significant $η…
