Abstract.

Using our analytical expressions that well model the lattice simulations of the gluonic excitations, we use the extended quark potential model to study the effects of orbital and radial excitations on the masses and sizes of conventional and hybrid \( B_c\) mesons. A non relativistic formalism is used to numerically calculate the wave functions using the shooting method; this also allows us to calculate the E1 , M1 radiative partial widths for conventional meson to meson and hybrid to hybrid transitions. We incorporate spin mixing and compare our calculated spectrum and decay widths with the available experimental \( B_c\) masses and the theoretically predicted spectra and decay widths by other groups. Our results can help consider both conventional and hybrid quantum numbers for \( B_c\) mesons as experimental results become available.
