The formations of the K(K), D(D), and B(B) meson-nucleus bound states in \rm16O, \rm40Ca, \rm90Zr, \rm197Au, and \rm208Pb nucleus are investigated using the quark meson coupling model. The model relies on a mean field description of non-overlapping nucleon bags bound by the self-consistent interactions of scalar (σ, δ) and vector (ω, ρ) mesons with the (anti)quarks inside the bags, which is further extended to explore the properties of nuclei. We estimate the meson-nucleus bound state energies by solving the Klein-Gordon equations with the real potentials calculated self-consistently within the model, using a coordinate space approach. The calculations are carried out for different nuclear interactions. The effects of Coulomb interaction are considered in the present study for the charged mesons. Our study indicates the formation of rather deeply bound B-mesic states at the very central region of the nuclei, compared to the D and K mesons, offering a more promising probe to explore subtle nuclear medium effects. The investigations of such bound states are of particular interest for the upcoming \rmPANDA at FAIR, J-PARC-E29, and JLab experiments.
