论文摘要
我们提出了一种蒙特卡洛方法，可在转向颜色的颜色上进行软绿色重新调整，该方法可用于改善现有的Parton淋浴算法。在单发性水平上，分裂功能的软性结合增强功能明确链接到二次Casimir操作员，而广角单秒增强功能则连接到非平凡的颜色相关器。我们专注于对所有订单的颜色矩阵校正校正的数值稳定实现，并通过在单一排放级别需要单位性来近似虚拟校正。我们提供了概念验证实施，以计算Lepton Colliders的非局部事件形状。
We present a Monte Carlo approach to soft-gluon resummation at subleading color which can be used to improve existing parton shower algorithms. At the single-emission level, soft-collinear enhancements of the splitting functions are explicitly linked to quadratic Casimir operators, while wide angle single-soft enhancements are connected to nontrivial color correlators. We focus on a numerically stable implementation of color matrix element corrections to all orders and approximate the virtual corrections by requiring unitarity at the single-emission level. We provide a proof-of-concept implementation to compute nonglobal event shapes at lepton colliders.
