英文摘要We investigate the tensor meson a(2)(1320) photon-production off proton in the gamma p -> na(2)(+) (1320) and gamma p -> n rho(0)pi(+) reactions within the effective Lagrangian approach and isobar model. For gamma p -> na(2)(+) (1320) reaction, by considering the contributions from only the t-channel pi(+) exchange, we get a fairly good description of the current experimental data for the total cross-section. Based on the theoretical results of the gamma p -> na(2)(+) (1320) reaction, we studied the role of a(2)(1320) meson in the gamma p -> n rho(0)pi(+) reaction, which mainly contributes to the gamma p -> n pi(+)pi(+)pi(-) reaction. The latter reaction has been measured by the CLAS Collaboration at the photon energy E-gamma around 5.1 GeV. For the gamma p -> n rho(0)pi(+) reaction, we pay attention to the low photon energy region where the contribution from a(2)(1320) meson is dominant, while the contribution from the pi(2)(1670) meson could be very small and hence can be neglected. The total cross-sections, invariant mass distribution and the Dalitz plot of gamma p -> n rho(0)pi(+) reaction are shown, which can be tested by future experiments.
