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 $χ_{c J} \to Λ Λ ˉ η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +566

By analyzing $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decays of $χ_{c J} \to Λ Λ ˉ η$ ( $J = 0$ , 1 and 2) ar…
