In this report we review recent theoretical progress and the latest
experimental results in jet substructure from the Tevatron and the LHC. We
review the status of and outlook for calculation and simulation tools for
studying jet substructure. Following up on the report of the Boost 2010
workshop, we present a new set of benchmark comparisons of substructure
techniques, focusing on the set of variables and grooming methods that are
collectively known as "top taggers". To facilitate further exploration, we have
attempted to collect, harmonise, and publish software implementations of these
techniques.

本文回顾了 Tevatron 和 LHC 中喷注亚结构的最新理论进展和实验结果，阐述了计算和模拟工具的现状和前景，重点讨论了称为 “顶标记器” 的变量和修整方法组合的一组基准比较，并尝试收集、协调和发布这些技术的软件实现，以促进进一步的探索。
