摘要
We investigate the Lambda(1520) photoproduction via the reaction process, gamma N -> K Lambda(1520). We employ the Born approximation and the Rarita Schwinger formalism is used for Lambda(1520). We reproduce the total cross sections and the various angular distributions qualitatively well for the proton target and estimate them for the neutron one. We find that the contact term contributes much more to the process than the other kinematical channels. Taking into account this fact, we reanalyze the K^*--exchange dominance hypothesis suggested by the previous experiments.
