ResumoWe have performed an experiment in the Antiproton Accumulator at Fermilab to study two-body neutral final states formed in ¯pp annihilations. Differential cross sections are determined in the center-of-mass energy range 2.911<√s<3.686 GeV for the final states π0π0, ηπ0, ηη, π0γ, and γγ. The energy dependence of differential cross sections at 90° in the center of mass is studied to test the predictions of phenomenological QCD scaling hypotheses which predict power-law dependence.Received 30 December 1996DOI:https://doi.org/10.1103/PhysRevD.56.2509©1997 American Physical Society
