Abstract

Assuming that the f2(1525), a2(1320), and K2*(1430) resonances are dynamically generated states from vector-meson–vector-meson interactions in the s-wave with spin S=2, we study the γpf2(1525)p, γpa20(1320)p, and γpK2*(1430)Λ(Σ) reactions. These reactions proceed in the following way: the incoming photon first mutates into a ρ0, ω, or ϕ meson via vector-meson dominance, which then interacts with the ρ0, ω, or K* emitted by the incoming proton to form the tensor mesons f2(1525), a2(1320), and K2*(1430). The picture is simple and has no free parameters, as all the parameters of the mechanism have been fixed in previous studies. We predict the differential and total cross sections of these reactions. The results can be tested in future experiments and therefore offer new clues about the nature of these tensor states.
