A Study of Excited b- 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 b- states, i.e. b(6316)-, b(6330)-, b(6340)-, and b(6350)-. Mass spectrum is obtained in Hypercentral Constituent Quark Model (hCQM) by solving six-dimensional nonrelativistic Schr\"odinger 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 b states within 3P0 model are calculated. Obtained results are presented with the comparison of available experimental data and other theoretical studies.
