Abstract

The spectroscopy of Ξ0\Xi^0 is performed within the relativistic framework of independent quark model. The equal mixture of scalar and vector components in the potential having Martin-like form is considered for the confinement. With the suitable potential parameters for Ξ0\Xi^0, mass spectra for high radial and orbital excitation is calculated. The experimentally observed values of ground state magnetic moment, branching ratios and asymmetry parameters for radiative weak decays, Ξ0Λ0+γ0\Xi^{0}\rightarrow\Lambda^{0} + \gamma^{0} \& Ξ0Σ0+γ0\Xi^{0}\rightarrow\Sigma^{0} + \gamma^{0} are obtained to validate the model. The spin parity of experimentally known resonances like Ξ(1530)\Xi(1530), Ξ(1820)\Xi(1820), \& Ξ(2030)\Xi(2030) are confirmed through the Regge trajectories in (J,M2)(J,M^2) plane. The spin pa+rity of Ξ(1950)\Xi(1950), Ξ(2130)\Xi(2130), \& Ξ(2250)\Xi(2250) are predicted using those Regge trajectories. The radiative decay width and magnetic moment of first resonance is also predicted.
