Abstract
Within an effective Lagrangian approach and resonance model, we study the
and
reactions via the
-exchange mechanism. For the
reaction, we perform a calculation of the differential and total cross-sections by considering the contributions of the
intermediate resonance decaying into
and then into
. Besides, the non-resonance process is also considered. With a lower mass of
, the experimental data for the invariant
mass distributions can be fairly well reproduced. For the
reaction, with the model parameters, the total cross-section is of the order of 10 μb at the photon beam energy
~2.5 GeV. It is expected that the model calculations in this work could be tested by future experiments.
