论文摘要
我们探讨了连接的有效的重型Y弦模型接近中间弦行为的极限。我们计算和比较diquark-Quark和Quark-Antiquark配置的静态电势和能量密度相关器的数值。量规模型是纯Yang-mills $ su（3）$晶格量规理论，耦合$β= 6.0 $和有限温度。 diquark设置近似为两个夸克，限制在半径$ 0.1 $ fm的球体内。电势和能量的晶格数据表明，绑定diquark-Quark配置的字符串与Quark-Antiquark限制字符串显示相同的行为。但是，随着温度升高到临界点$ t_ {c} $的足够小的社区，两个系统之间的gluonic相似性在很短的情况下也不明显，也没有中间距离尺度$ r <1.0 $ fm。两个系统的动作密度相关器的电势和第二矩之间的比较显示出明显的分裂。这表明，生存的Baryonic解耦状态与中间光谱重叠。 Baryonic交界处的电势和配置文件模型非常适合Diquark-Quark布置的数值晶格数据。但是，在临界点附近，与相应的Quark-Antiquark数据的拟合相比，中间字符串显示出较大的偏差。
We explore the limit at which the effective baryonic Y-string model of the junction approaches the mesonic stringlike behavior. We calculate and compare the numerical values of the static potential and energy-density correlators of diquark-quark and quark-antiquark configurations. The gauge model is pure Yang-Mills $SU(3)$ lattice gauge theory at coupling $β=6.0$ and finite temperature. The diquark setup is approximated as two quarks confined within a sphere of radius $0.1$ fm. The lattice data of the potential and energy show that the string binding the diquark-quark configuration displays an identical behavior to the quark-antiquark confining string. However, with the temperature increase to a small enough neighborhood of the critical point $T_{c}$, the gluonic similarities between the two systems do not manifest neither at short nor intermediate distance scales $R<1.0$ fm. The comparison between the potential and the second moment of the action-density correlators for both systems shows significant splitting. This suggests that subsisted baryonic decoupled states overlap with the mesonic spectrum. The baryonic junction's model for the potential and the profile returns a good fit to the numerical lattice data of the diquark-quark arrangement. However, near the critical point, the mesonic string displays large deviations compared to fits of the corresponding quark-antiquark data.
