Evidence for $η_{c} (2 S) \to p p ˉ π^{+} π^{-} π^{0}$ and observation of $χ_{c J} \to p p ˉ π^{+} π^{-} π^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +771

Using $(2.712 \pm 0.014) \times 1 0^{9}$ $ψ (3686)$ events collected by the BESIII detector at the BEPCII collider, the $ψ (3686) \to γ p p ˉ π^{+} π^{-} π^{0}$ process is investigated. Evidence…

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…

Measurement of Born Cross Sections for $e^{+} e^{-} \to K^{+} I^^{0} I^ˉ £^{-}$ at $s = 3.51 - 4.95$ GeV and Observation of $I ¨ (3770) \to K^{+} I^^{0} I^ˉ £^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +771

Using 44.55 fb $^{- 1}$ of $e^{+} e^{-}$ collision data collected by the BESIII detector at the BEPCII collider, we report the first measurement of the Born cross sections for the $e^+e^-…
