Motivated by great progress in experiments in searching of the heavy baryons, in the present work we systematically analyze the mass spectra and the properties of singly bottom and doubly heavy baryons. The relation between Regge slopes, intercepts, and baryon masses are derived under the assumption of linear Regge trajectories. Using these relations we evaluated the Regge slopes (
) of these heavy baryons and obtain the orbitally excited state masses in the 
plane. Similarly, the Regge parameters (
and 
) are estimated for each Regge line in the 
plane and the radially excited state masses are obtained. We have updated our previously computed results with recent experimental observations. Also, in this work we have incorporated the experimental errors in the obtained results wherever the experimental inputs are taken. Further the Regge trajectories are plotted for our calculated masses in both the (
) and (
) planes. Also, by utilising the estimated mass values from our employed model, we calculate the other properties like strong decay widths of singly bottom baryons, also the magnetic moment and radiative decay width of these heavy baryons. We compared our estimated results with the experimental data and other theoretical predictions. The spin-parity of recently observed experimental bottom resonances are assigned this work.
