Observation of ${\chi }_{cJ}\to 3(K^{+}{K}^{-})$

BESIII Collaboration, M. Ablikim, M. N. Achasov +642

By analyzing $(27.12\pm 0.14)\times 10^8$ $\psi (3686)$ events collected with the BESIII detector operating at the BEPCII collider, the decay processes ${\chi }_{cJ}\to 3(K^{+}{K}^{-})$ ($J=0,1,2$)…
