Scientific paper

The $J/\Psi$ decay into a baryon pair and a pseudoscalar meson is computed, for some channels, in lowest order in perturbative QCD, modeling the baryon with a quark-diquark system. We use a set of parameters that has been proposed by some authors in order to fit the proton magnetic form factor $G^{p}_{M}$, the angular distribution of protons in the process $\gamma \gamma \to p \bar{p}$ and the width of $\eta_{c} \to \gamma \gamma$.
