QCD中矢量介子的真空结构

The Vacuum Structure of Vector Mesons in QCD

Fabian Rennecke

摘要:

利用泛函重整化群方法研究了真空中双味QCD中矢量介子的手征动力学。这使我们能够捕捉到从高能夸克胶子相到低能强子相的动力学跃迁,而不需要调整模型参数。我们用它来分析矢量介子质量向手征对称性破缺标度的标度、高能介子的退耦以及矢量介子占优的有效性。

英文摘要:

We study the chiral dynamics of vector mesons in two-flavor QCD in vacuum by utilizing a functional renormalization group approach. This allows us to capture the dynamical transition from the quark-gluon phase at high energies to the hadronic phase at low energies without the necessity of model parameter tuning. We use this to analyze the scaling of vector meson masses towards the chiral symmetry breaking scale, the decoupling of the mesons at high energies and the validity of vector meson dominance.
