喷流定义和理解的最新进展

Recent progress in defining and understanding jets

Gavin P. Salam

摘要:

这次演讲回顾了强子对撞机喷流发现在过去几年中的一些关键发展,包括:技术进步,如完整的红外安全无籽锥算法和快速计算方法,如KT算法,以及通用的方法减去堆积顺序重组喷流发现;在理解喷流算法对潜在事件和强子化的敏感性方面取得的进展;以及利用我们对QCD发散的知识来更好地定义和预测重味喷流截面的工作。

英文摘要:

This talk reviews some key developments that have taken place in hadron-collider jet finding over the past couple of years, including: technical advances such as the complete formulation of an infrared safe seedless cone algorithm and fast computational approaches to sequential recombination jet finders like the kt algorithm, together with universal methods for subtracting pileup; progress in understanding the sensitivity of jet algorithms to the underlying event and hadronisation; and work that exploits our knowledge of QCD divergences to better define and predict heavy-flavour jet cross sections.
