摘要：

The model is presented to describe the f(2)(1270) meson photoproduction as a result of pion-pion interactions in the final state. Treating tensor mesons as objects dynamically created due to final state interactions is a convenient and straightforward way to employ data from pi pi scattering like phase shifts and inelasticities for description of (photo) production reactions while retaining proper analytical structure of amplitudes, two-particle unitarity, and crossing symmetry. The model presented here can provide experimentally testable quantities like differential cross sections and pi pi mass distributions as well as the strengths of partial waves corresponding to various f(2)(1270) helicities which are essential for partial wave analyses. It can also be used to compute moments of angular distribution and spin density matrix elements where partial wave interference effects are important.
