Study of Heavy Baryons Phenomenology

The objective of this research is to investigate the properties of singly heavy baryons within the framework of the constituent quark model. This study focuses on calculating the mass spectra and the strong and electromagnetic decay widths for singly bottom baryons, as well as the electromagnetic decay widths for singly charmed baryons. The mass spectra are computed using a quark model, while the 3P0 model is employed to analyze the open-flavor strong decay channels of singly bottom baryons. The electromagnetic decay widths for singly bottom baryons are calculated up to the second shell states using the Hamiltonian of electromagnetic interactions in the nonrelativistic approximation. For singly charmed baryons, the electromagnetic decay widths are specifically determined for the Ξc P-wave states. A novel method is introduced for the calculation of electromagnetic decay widths. This innovative approach enables the completely analytical evaluation of transition amplitudes without introducing any additional approximations used in previous articles in the heavy baryon sector. Notably, this work represents the first theoretical study of the electromagnetic decays of Dρ -wave states, ρλ mixed states, and radially excited ρ and λ states.
