We investigate the productiong of f2(1270) and f2'(1525) mesons in the K-p→Λf2(1270),K-p→Λf'2(1525) and K-p→K+K-Λ reactions within an effective Lagrangian approach. For K-p→f2Λ reaction, by considering the contributions from the t-channel K+ exchange and u-channel nucleon pole, we get a fairly good description of the experimental measurements about the total and differential cross sections. Based on the studies of the K-p→f2Λ reaction, we investigate K-p→K+K-Λ reaction including the contributions from the f2(1270) and f'2(1525) mesons decaying into K+K- pair. The total cross sections and invariant mass distribution of the K p → K+K- Λ reaction are predicted. The results can be tested in future experiments and therefore offer new clues on the nature of these tensor states.
