Abstract
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 − .

The properties of baryons reflect the strong interaction at low energy region
Investigation of the spectrum and the properties of baryons relies on phenomenological models of Quantum Chromodynamics (QCD) such as quark models, bag models, soliton models, etc
Summary
The properties of baryons reflect the strong interaction at low energy region. The underlying theory of strong interaction in the standard model is Quantum Chromodynamics (QCD). [2,3,4,5].) most works are limited by employing only a few interaction terms, and, it is hard to compare the extracted coupling constants to the predictions of phenomenological models for hadron structure. We use a general formalism to treat high-spin baryon resonances by adopting the method developed by Fronsdal et al based on the Rarita-Schwinger formalism. This includes the most general forms of the effective Lagrangians describing the interactions of baryon resonances.
