HERA ep散射中的多部分子相互作用

Multiparton interactions in ep scattering at HERA

H. Jung

摘要:

在HERA的光生区的喷流生产的测量,这是敏感的底层事件结构。有人认为,在光生区域中,需要大量的多部分子相互作用的共线因式分解分析来描述测量。高阶部分子辐射(CCFM部分子簇射)的不同方法也可以描述测量。

英文摘要:

Measurements of jet production in the photoproduction region at HERA are presented, which are sensitive to the underlying event structure. It is argued that in the photoproduction region a significant amount of multi-parton interactions in the collinear factorisation ansatz are needed to describe the measurement. A different approach for higher order parton radiation (CCFM parton showers) can also describe the measurement.
