具有明确手征对称性破缺的夸克-介子模型中的非均匀相

Inhomogeneous phases in the quark-meson model with explicit chiral-symmetry breaking

Michael Buballa, Stefano Carignano, Lennart Kurth

摘要:

研究了具有明确手征对称性破缺的夸克-介子模型中非均匀手征相的存在性。我们发现非均匀区随π介子质量的增加而缩小,但在m_pi的物理值不变的情况下仍然存在。在标量通道中,对非均匀物质的不稳定性发生,而赝标量模式是不利的。

英文摘要:

We investigate the existence of inhomogeneous chiral phases in the quark-meson model with explicit chiral-symmetry breaking. We find that the inhomogeneous region shrinks with increasing pion masses but survives for the physical value of m_pi. The instability towards inhomogeneous matter occurs in the scalar channel, while pseudoscalar modes are disfavored.
