论文摘要
我们研究了最近讨论的“完全包容性喷射相关器”的特性和结构，即，衡量的场相关器表征了自由夸克产生的最终状态哈德子，因为这在真空中传播。在操作员级别上工作，我们将此对象连接到夸克的单人物片段化相关器，并利用一种新型的规格不变的光谱分解技术来得出夸克碎片功能的完整动量总和规则，最高为twist-3级别；恢复已知结果，并提出了新的总和规则。然后，我们展示如何通过研究包容性喷射量规质量术语来明确连接夸克强调和动态夸克质量产生。一方面，这种质量与夸克的集成手性光谱函数有关，另一方面，通过$ e $和$ \ tilde {e} $ twist-3碎片函数函数总规则可以在实验上访问。因此，这些碎片化功能在深度非弹性过程中的测量为量子染色体动力学质量的动态产生提供了一个实验网关。
We investigate the properties and structure of the recently discussed "fully inclusive jet correlator", namely, the gauge-invariant field correlator characterizing the final state hadrons produced by a free quark as this propagates in the vacuum. Working at the operator level, we connect this object to the single-hadron fragmentation correlator of a quark, and exploit a novel gauge invariant spectral decomposition technique to derive a complete set of momentum sum rules for quark fragmentation functions up to twist-3 level; known results are recovered, and new sum rules proposed. We then show how one can explicitly connect quark hadronization and dynamical quark mass generation by studying the inclusive jet's gauge-invariant mass term. This mass is, on the one hand, theoretically related to the integrated chiral-odd spectral function of the quark, and, on the other hand, is experimentally accessible through the $E$ and $\tilde{E}$ twist-3 fragmentation function sum rules. Thus, measurements of these fragmentation functions in deep inelastic processes provide one with an experimental gateway into the dynamical generation of mass in Quantum Chromodynamics.
