论文摘要
$ SU（3）$中心涡流对Landau-Gauge Gluon繁殖器的影响是在动态费用存在下计算的，并与纯Yang-Mills案相比。与已建立的纯形结果相比，发现动态费米子的存在会改变中心涡流传播器的行为。还从中心涡流的角度探索了Gluon光谱表示，其中表现出中心涡流显示出明显的阳性违规迹象，这是限制的指标。涡旋去除随后恢复了阳性，表明振动束的关键中心涡流起着至关重要的中心涡流。
The impact of $SU(3)$ centre vortices on the Landau-gauge gluon propagator is calculated in the presence of dynamical fermions and compared to the pure Yang-Mills case. The presence of dynamical fermions is found to alter the behaviour of the centre vortex propagator when compared to the established pure-gauge result. The gluon spectral representation is also explored from the centre vortex perspective, where centre vortices are shown to exhibit clear signs of positivity violation, which is an indicator of confinement. Vortex removal subsequently restores positivity, demonstrating the crucial role centre vortices play in the confinement of gluons.
