Helicity amplitude and branching fraction measurement of $I ¨ _{c J} \to I^ I^ˉ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

Utilizing $2712.4 \pm 14.3$ million $I ¨ (3686)$ events accumulated by the BESIII experiment, we perform a partial wave analysis of $Ï(3686)\rightarrowÎ³Ï_{cJ}\rightarrowÎ³Î\barÎ…

First Measurement of the Absolute Branching Fraction of $I^\cdot_{c} \to I^^{3} I^^{3}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +691

We apply a tag-and-probe method to precisely measure the absolute branching fraction of the decay $I^\cdot_{c} \to I^^{3} I^^{3}$ with the BESIII experiment at BEPCII. Starting with a large initia…
