Is There Window for a "Supersoft" Pomeron in J/ψ Photoproduction at Low Energy?

概要

• 論文の詳細を見る

• The low energy J/ψ photoproduction cross-section has been studied using the Pomeron model. To account for the discrepancy between experimental data and predictions of conventional models, i.e. the sum of the soft Pomeron with intercept 1.08 and the hard Pomeron with intercept 1.418, a Regge trajectory associated with a scalar meson (f, a) exchange, which we call a "supersoft" Pomeron, is introduced. To distinguish the conventional model from that with this new additional Pomeron, proposed observations related to other polarization observables in upcoming polarized experiments are discussed.
