Abstract
The decay rate for →pp¯ is computed at the tree level in perturbative QCD, modeling the proton with a quark-diquark system. Satisfactory agreement with the data is obtained. Comparisons with pure-quark models are made and predictions are given for this and other heavy-pseudoscalar-meson decay rates into baryon-antibaryon.
