论文摘要
量规理论的大$ N_C $或拓扑平面极限可以被视为经典限制，因为所有仪表玻色子都是可区分的颗粒，因此无法表现出干扰。因此，由于颜色流而引起的量子效应，从$ 1/n_c $开始时出现。我们引入了运动学观察物，明确地对从干涉与平方颜色排序振幅的比率形成的均匀颜色的效果明确敏感。这样的可观察物通常不是红外线和共线安全，因此我们引入了由适当的多点能量相关因子定义的角度可观察物，这些相关因子以颜色订购的幅度的形式促进。我们证明了颜色干扰效应在最简单的系统中表现为正弦振荡，这是一种带有三个颗粒的共线射流，并显示了预测这种可观察到的这种可观察到的局限性，该仪表可观察到在通用的，前彩的parton淋浴蒙特卡洛斯。
The large-$N_c$ or topologically planar limit of gauge theories can be considered as a classical limit because all gauge bosons are distinguishable particles and therefore cannot exhibit interference. Quantum effects due to the flow of color therefore arise starting at subleading in $1/N_c$. We introduce kinematic observables explicitly sensitive to effects at subleading color formed from the ratio of interfering to squared color-ordered amplitudes. Such observables are in general not infrared and collinear safe, so we introduce angular observables defined from appropriate multi-point energy correlators motivated by the form of color-ordered amplitudes. We demonstrate that color interference effects are manifest as sinusoidal oscillation in the simplest system, a collinear jet with three particles, and show the limitations of predicting this observable in all-purpose, leading-color parton shower Monte Carlos.
