abstract = "The first few moments of the wave functions for Δ's and Ω are evaluated by QCD sum rules. Model wave functions are constructed based on these moments. Perturbative QCD predictions of cross sections for γγ → Δ++Δ++ and γγ → ΩΩ are obtained by integrating the quark scattering amplitudes over these wave functions. The ratio of γγ → Δ++Δ++ and γγ → p p{\= } cross sections is much lower than would be naively expected. Predictions for γγ → B8B8 are also given for the full baryon octet with QCD sum-rule wave functions.",

note = "Funding Information: Two ingredients are needed to obtain a quantitative prediction for the amplitude of an exclusive process: the hard kernel of the reaction, calculable from QCD perturbation theory, and the nonperturbative wave functions of the hadrons entering the process. In ref. \[9\]a method was described which enormously simplifies the a Supported in part by NSF PHY-84-15535-05. 2 Supported by Rutgers Supercomputer Postdoctoral Fellowship and Virginia Polytechnic Institute and State University.",
