Description

A new top jet tagging algorithm ({\tt CATopTag}) is presented, that uses the Cambridge-Aachen jet finding algorithm to decompose highly boosted top jets into subjet components and examine kinematics of those subjets. It is found that this algorithm has a rejection rate of approximately 98\% for non-top jets with $p_T=600$ GeV/$c$, while retaining approximately 46\% of top jets with $p_T>600$ GeV/$c$.
