A Study of Excited Ωb- States in Hypercentral Constituent Quark Model via Artificial Neural Network

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 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.
