Study of the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +640

We report the first measurement of the di-electron invariant mass dependent transition form factor in the electromagnetic Dalitz decay $J / ψ \to e^{+} e^{-} π^{0}$ using $(10087 \pm 44) \ti…

Helicity amplitude analysis of $χ_{c J} \to ϕϕ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +567

Using (447.9 $\pm$ 2.3) million $ψ$ (3686) events collected with the BESIII detector, the decays of $χ_{c J} \to ϕϕ$ ( $J$ =0, 1, 2) have been studied via the decay $ψ(3686)\ri…

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…
