Description
In this report, we discuss some aspects of the present theoretical status of the pentaquarks. In the first part we discuss the importance of the pion interaction due to spontaneous symmetry breaking of chiral symmetry, which affects the basic property such as the parity of Θ+. In the second part we show some calculations for the photoproduction of Θ+ and Λ(1520) in the effective Lagrangian approach. Within the minimal setup of the model, we make comments in comparison with the present controversial experimental results
