论文摘要
在高于所涉及的质量尺度的粒子碰撞中,共线分裂成为主要现象。在此制度中对物理的适当描述包括Parton分布函数,初始状态辐射,最终状态辐射和碎片函数。以一致的理论处理来制定这些功能,并为应用提供适当的形式主义,这是至关重要的,这是由于最近对多TEV能源制度的党派散射的讨论所激发的。在本报告中,我们简要介绍了最终对数的重新召集,作为电子片过程的碎片函数。作为一个明确的例子,我们研究了在该过程中$ pp \ to wzj $的electroweak仪表玻色子分裂,并证明了片段化的重要效果。
In particle collisions at energies higher than the mass scale involved, the collinear splitting becomes the dominant phenomena. Suitable descriptions of the physics in this regime include the parton distribution functions, the initial state radiations, the final state radiations and the fragmentation functions. It is of fundamental importance to formulate those functions with consistent theoretical treatments, and to provide the adequate formalism for applications, as motivated by the recent discussions of partonic scatterings at the multi-TeV energy regime. In this report, we briefly present the resummation of the final-state logarithms as fragmentation functions for the electroweak processes. As an explicit example, we study an electroweak gauge boson splitting in the process $pp\to WZj$ and demonstrate the important effects from the fragmentation.
