Abstract
In this work, we have obtained mass spectra, radiative decay widths and strong decay widths of newly observed excited \(\Omega _b^-\) states, i.e. \(\Omega _b(6316)^-\), \(\Omega _b(6330)^-\), \(\Omega _b(6340)^-\), and \(\Omega _b(6350)^-\). Mass spectrum is obtained in Hypercentral Constituent Quark Model (hCQM) by solving six-dimensional nonrelativistic Schrödinger equation via Artificila Neural Network (ANN). In this respect, radiative decay widhts are calculated by a generalization of a framework from meson to baryon. Also, strong decay widths of the low-lying \(\Omega _b\) states within \(^3P_0\) model are calculated. Obtained results are presented with the comparison of available experimental data and other theoretical studies.
