论文摘要
我们带来的证据表明，最近发现的高能重新调整自然稳定性的特性直接连接到重物的碎片化机制。作为一种现象学支持，我们为重击头标签敏感的差分分布提供了预测，该分布在jethad多蚀刻代码中实现的混合高能量/纯净分解（NLL/NLO）的近代领先对数水平（NLL/NLO）进行了预测。我们表明，稳定机制是在从数据中提取的两个重味共线片段函数的GLUON通道中编码的，并且从非偏见的QCD输入中演变出来。
We bring evidence that the recently discovered property of natural stability of the high-energy resummation is directly connected to the fragmentation mechanism of heavy hadrons. As a phenomenological support, we provide predictions for differential distributions sensitive to heavy-hadron tags, calculated at the next-to-leading logarithmic level of the hybrid high-energy/collinear factorization (NLL/NLO), as implemented in the JETHAD multimodular code. We show that the stabilizing mechanism is encoded in gluon channels of both heavy-flavor collinear fragmentation functions extracted from data and the ones evolved from a non-relativistic QCD input.
