Nucleon resonances in the γp → ϕK+ Λ reaction near threshold

الأصل · EN

We investigate the γp → ϕK+ Λ reaction near threshold within an effective Lagrangian approach and the isobar model. Various nucleon resonances caused by the π and η meson exchanges and background contributions are considered. It is shown that the contribution from the N*(1535) resonance caused by the η meson exchange plays the predominant role. Hence, this reaction provides a good new platform to study the N*(1535) resonance. The predicted total cross section and specific features of angular distributions can be tested by future experiments.
