We investigate the nuclear and quark matters at finite real chemical potential (${\mu }_{\mathrm{R}}$) and low temperature from the viewpoint of the canonical sectors constructed via the imaginary chemical potential region. Based on the large $N_{\mathrm{c}}$ estimation, where $N_{\mathrm{c}}$ is the number of colors, we can discuss the confinement-deconfinement nature at finite ${\mu }_{\mathrm{R}}$ from the canonical sectors. We find the expectation that the sharp changes of canonical sectors at ${\mu }_{\mathrm{R}}\sim M_{\mathrm{B}}/N_{\mathrm{c}}$, where $M_{\mathrm{B}}$ is the lowest baryon mass, happens in the large $N_{\mathrm{c}}$ regime, and it is matched with the quarkyonic picture. In addition, we discuss the color superconductivity and the chiral properties from the structure of canonical sectors. Even in the present anatomy from the canonical sectors, we obtain a suitable picture for the dense QCD matter.

来自标准扇区的致密 QCD 物质的解剖

我们研究了有限真实化学势下的核和夸克物质（${\mu }_{\mathrm{电阻}}$) 和低温，从通过假想化学势区域构建的规范扇区的角度来看。基于大$N_{\mathrm{C}}$ 估计，其中 $N_{\mathrm{C}}$ 是颜色的数量，我们可以在有限的情况下讨论限制 - 解除限制的性质 ${\mu }_{\mathrm{电阻}}$来自规范部门。我们发现规范部门的急剧变化在${\mu }_{\mathrm{电阻}}～{米}_{\mathrm{乙}}/N_{\mathrm{C}}$， 在哪里 ${米}_{\mathrm{乙}}$ 是最低的重子质量，发生在大 $N_{\mathrm{C}}$政权，它与夸克子图相匹配。此外，我们从规范扇区的结构讨论了颜色超导性和手性特性。即使在目前的规范扇区解剖中，我们也获得了密集 QCD 物质的合适图片。
