Title:
A Fragmentation Approach to Jet Flavor
Speaker:
Abstract:
Intuitive or de facto definitions of jet flavor are typically only well-defined in the deep UV, where a jet consists of a single particle. However, measurements are performed in the IR, and any practical definition of jet flavor can only access information in the IR. In this talk, I will introduce a novel definition of jet flavor defined as the particle in the jet whose momentum lies exactly on the Winner-Take-All recombination scheme axis. I will also derive linear evolution equations of this WTA flavor in flowing from the UV to the IR that are a small modification to traditional DGLAP and demonstrate quantitative agreement with parton shower Monte Carlos.
