Understanding strong interactions at low energy region requires the precise knowledge on the spectra and the properties of hadrons. Such informations can be obtained through detailed and sophisticated analyses of experimental data collected from various scattering processes using electromagnetic beams or hadron beams. At present, there have been a lot of precise data collected for the production of meson-baryon final states in photon-nucleon and nucleon-nucleon scattering processes. Since the total centerof- mass energy range of such scattering experiments covers the resonance region of about 2 GeV, it is legitimate to include as many baryon resonances as possible in the analyses of the data, which requires the formalism to describe high-spin baryon resonances. Here, we use the Fronsdal method to describe high-spin baryon resonances and develop their interaction Lagrangians. We then apply this method to investigate the role of high-spin baryon resonances in the reactions of γp → KΣ(1385) and γp → K+K+Ξ−.
