Observation of $I^\cdot_{c} \to p p ˉ I^\cdot$ via $I ¨ (3686) \to I^^{3} p p ˉ I^\cdot$

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

The study reports the first observation of the decay η_c → p p̄ η using a large ψ(3686) data set collected with the BESIII detector, and determines its branching fraction while acc…

Observation and branching fraction measurements of $J / I ¨ \to p p ˉ K_{S}^{0} K_{S}^{0}$ and $I ¨ (3686) \to p p ˉ K_{S}^{0} K_{S}^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +765

Using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / I ¨ $ events and $(2.712 \pm 0.014) \times 1 0^{9}$ $I ¨ (3686)$ events collected by the BESIII detector operating at the BEPCII collider, we report the…
