Özet
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 Schrodinger 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 3P0 model are calculated. Obtained results are presented with the comparison of available experimental data and other theoretical studies.
