Observation of the charmonium decay $I^\cdot_{c} \to I^^{3} I^^{3}$ in $J / I ¨ \to I^^{3} I^\cdot_{c}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +662

Using $(2712.4 \pm 14.3) \times 1 0^{6}$ $I ¨ (3686)$ events collected with the BESIII detector at the BEPCII collider, the decay $I^\cdot_{c} \to I^^{3} I^^{3}$ in $J / I ¨ \to I^^{3} I^\cdot_{c}$ is observed. We determin…
