  [1]Abstract: This is a contribution for the PANIC 2021 Proceedings based on
the articles, Eur. Phys. J. A 57, 259 (2021) and the accompanied article
$[$arXiv:2109.08636 $[$hep-ph$]]$ (Hadron 2021 contribution). We have estimated
for the first time the mass shifts of the $\Upsilon$ and $\eta_b$ mesons in
symmetric nuclear matter by an SU(5) flavor symmetric effective Lagrangian
approach, as well as the in-medium mass of $B^*$ meson by the quark-meson
coupling (QMC) model. The attractive potentials for the $\Upsilon$- and
$\eta_b$-nuclear matter are obtained, and one can expect for these mesons to
form nuclear bound states. We have indeed found such nuclear bound states with
$^{12}$C nucleus, where the results for the $^{12}$C nucleus bound state
energies are new, and we report here for the first time. [2]Abstract: We
estimate for the first time the mass shifts (scalar potentials) in symmetric
nuclear matter of the $\Upsilon$ and $\eta_b$ mesons using an effective
Lagrangian approach, as well as the in-medium mass of the $B^*$ meson by the
quark-meson coupling model. The attractive potentials of both $\Upsilon$ and
$\eta_b$ are expected to be strong enough for these mesons to be bound to the
$^4$He nucleus, and we have obtained such nuclear bound state energies.
