Search for $η_{c} (2 S) \to p p ˉ$ and branching fraction measurements of $χ_{c J} \to p p ˉ$ via $ψ (2 S)$ radiative decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +648

Using $(27.12 \pm 0.14) \times 1 0^{8}$ $ψ (2 S)$ events collected by the BESIII detector operating at BEPCII, we search for the decay $η_{c} (2 S) \to p p ˉ$ via the process $ψ(2S)\to γη…

Search for the rare decay $J / ψ \to γ D^{0} + c . c .$ at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using $(10087 \pm 44) \times 1 0^{6} J / ψ$ events collected with the BESIII detector, we search for the rare decay $J / ψ \to γ D^{0} + c . c .$ for the first time. No obvious signal is observed and t…

Search for $h_{c} \to π^{+} π^{-} J / ψ$ via $ψ (3686) \to π^{0} h_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +657

Using $(2712.4 \pm 14.3) \times 1 0^{6} ψ$ (3686) events collected with the BESIII detector operating at the BEPCII collider, we search for the hadronic transition $h_{c} \to π^{+} π^{-} J / ψ$ …
