The main decay of $ J / \psi $ is $ c \bar{c} \to ggg $. How can this reaction channel be observed? 3 gluons will hadronize immediately, or not?

If you look at the data from the PDG, you see that the decay into three gluons is part of the decay mode into hadrons: $\Gamma_1 \approx \Gamma_2 + \Gamma_3 +\Gamma_4$.
