论文摘要
在存在局部平等介质的情况下，光矢量介子具有手性不平衡的特性，在矢量 - 梅森优势模型中被考虑。使用有限的最低降低辐射诱导的局部有效的Lagangian，最初是为QED开发的，为vector $ρ$和$ω$中的媒介，我们获得了质谱，这是动量和手性化学势$μ_5$的函数。我们表明，除了Chern-simons术语外，分裂了介子的横向极化外，还有另一个辐射诱导的贡献，在动量下变得很重要，$μ_5$在几百meV左右。
The properties of the light vector mesons in the presence of local parity breaking medium with a chiral imbalance are considered in the vector-meson dominance model. Applying the finite lowest-order radiatively induced local effective Lagrangian, initially developed for the QED, for the vector $ρ$ and $ω$ mesons, we obtained the mass spectrum as a function of momentum and chiral chemical potential $μ_5$. We showed that in addition to the Chern-Simons term, splitting the transverse polarisations of the mesons, there is another radiatively induced contribution that becomes important at momentum and $μ_5$ around a few hundred MeV.
