    Spectroscopic properties of Baryons

    Chandni Menapara🇮🇳 · Zalak Shah🇮🇳 · Ajay Kumar Rai🇮🇳

    The resonance state of baryon existing in four isospin () states, has been studied using Hypercentral Constituent Quark Model (hCQM) with a simple linear potential with added first order correction. The calculated data range for 1S-5S, 1P-5P, 1D-4D and 1F-2F with possible spin-parity assignments of all the states. The magnetic moments have also been obtained for all four configuration. The decay channel width has been calculated for few states. The linear nature of the data has been verified through Regge trajectories.

    The nature of nucleon resonances is still being debated, while much experimental data are accumulated. In this work, we focus on the negative parity resonance which is located in the scattering region of various meson-baryon coupled channels, and such dynamics can be crucial in understanding its properties. To test the relevance of such hadron dynamics, we investigate the decay properties of in detail. We examine how a two pole nature of is compatible with its observed decay properties. Moreover, we find that the resonance decays into final states involving and , where the latter is not yet observed experimentally. Such decay processes can be useful to study the properties of the aforementioned hyperon resonances.
