论文摘要

$η_C$ -Nucleus绑定的状态能量是针对各种核的。计算的基本输入,即中等修饰的$ d $和$ d^{*} $梅森质量以及核中的密度分布,在夸克 - 梅森耦合(qmc)模型中计算。核介质中$η_c$梅森的有吸引力的潜力来自中等内的$ dd^{*} $循环。我们的结果表明,$η_C$梅森应与所有考虑的核形成结合状态。

$η_c$-nucleus bound state energies are calculated for various nuclei. Essential input for the calculations, namely the medium-modified $D$ and $D^{*}$ meson masses, as well as the density distributions in nuclei, are calculated within the quark-meson coupling (QMC) model. The attractive potentials for the $η_c$ meson in the nuclear medium originate from the in-medium enhanced $DD^{*}$ loops in the $η_c$ self-energy. Our results suggest that the $η_c$ meson should form bound states with all the nuclei considered.
