Υ and ηb nuclear bound states

Upsilon and eta(b) nuclear bound-state energies are calculated for various nuclei, neglecting any possible effects of the widths. Essential input for the calculations, namely, the medium-modified B and B* meson masses, as well as the density distributions in nuclei, are calculated within the quark-meson coupling (QMC) model. The attractive potentials for the Upsilon and eta(b) mesons in nuclei are calculated from the mass shifts of these mesons in nuclear matter in the local density approximation. These potentials originate from the in-medium enhanced BB and BB* loops in their respective self-energy. After an extensive analysis we conclude that our results suggest that the Upsilon and eta(b) mesons should form bound states with all the nuclei considered.

In this study, the nuclear bound-state energies of Upsilon and eta(b) mesons were calculated for various nuclei, neglecting any effects of widths. The medium-modified B and B* meson masses, as well as the density distributions in nuclei, were calculated using the quark-meson coupling (QMC) model. The attractive potentials for Upsilon and eta(b) mesons in nuclei were calculated based on the mass shifts of these mesons in nuclear matter. The results suggest that Upsilon and eta(b) mesons should form bound states with all the nuclei considered.
