STUDY OF J/PSI THREE-BODY DECAYS INVOLVING BARYONS
Abstract
Description
The $J/Ψ$ 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 $γγ\to p \bar{p}$ and the width of $η_{c} \to γγ$.
