Abstract

Exclusive production of proton-antiproton pairs by two photon scattering at CM energies between 2.0 GeV and 3.1 GeV has been measured with the TASSO detector at the e⁺e^- storage ring PETRA. The angular distribution is flat within the accepted CM angular range |cos Θ^*|≤0.7. The integrated cross section (|cos Θ^*|≤0.6) drops from about 4 nb at 2 GeV to less than 0.5 nb above 3 GeV. For the two-photon production of the η_c(2984) and its subsequent decay into proton-antiproton the upper limit Γ(η_c→γγ)·B(η_c→pp)
