物质中$π$ - $η$混合和电荷对称性破坏NN势
$π$-$η$ mixing and charge symmetry violating NN potential in matter
摘要：
在离壳层修正下，我们构造了由$π$ - $η$介子混合引起的密度相关$III$类电荷对称性破坏（CSV）势.密度依赖性通过由中子-质子质量差和它们的不对称密度分布驱动的非零$π$ - $η$混合进入。密度相关的CSV势的贡献被发现是明显大于真空CSV势的贡献。
英文摘要：
We construct density dependent Class $III$ charge symmetry violating (CSV) potential due to mixing of $π$-$η$ meson with off-shell corrections. The density dependence enters through the non-vanishing $π$-$η$ mixing driven by both the neutron-proton mass difference and their asymmetric density distribution. The contribution of density dependent CSV potential is found to be appreciably larger than the contribution of vacuum CSV potential.
