The mass spectrum ofcb meson is investigated with an effective quark-antiquark potential of the form -α_c/r +Ar^νwith ν varying from 0.5 to 2.0. TheS andP-wave masses, pseudoscalar decay constant, weak decay partial widths in spectator model and the lifetime ofB_cmeson are computed. The properties calculated here are found to be in good agreement with other theoretical and experimental values at potential index,ν = 1

Heavy flavor baryons containing single and double charm (beauty) quarks with light flavor combinations are studied using the hypercentral description of the three-body problem. The confinement potential is assumed as hypercentral Coulomb plus power potential with power index 𝜈. The ground state masses of the heavy flavor, $J^{P} = \dfrac{1}{2}^{+}$ and $\dfrac{3}{2}^{+}$ baryons are computed for different power indices, 𝜈 starting from 0.5 to 2.0. The predicted masses are found to attain a saturated value in each case of quark combinations beyond the power index $\nu = 1.0$.

Triply heavy baryons with quark content ccb andcbb are investigated within the framework of Regge phenomenology. With the assumption of linear Regge trajectories, we have extracted the relations between Regge parameters and baryon masses. Using these relations,we compute the ground-statemasses of Ω$_{ccb}$ and Ω$_{cbb}$ baryons. Further, the Regge slopes and intercepts are estimated for these baryons to obtain the excited state masses in the (J, M$^2$) and (n, M$^2$) planes. Also, using the obtained results we calculated other properties like magnetic moment and radiative decay width of these triply heavy baryons. We compared our evaluated results with those obtained by other theoretical approaches, and our results show a general agreement with them. The present study and our predictions will provide significant clues for future experimental research of these unseen triply heavy baryons.
