Description
We consider the issue of meaningfully assigning a flavor label to a jet and we show that modern jet substructure techniques can give us new ways to tackle this problem.
On the one hand, we introduce a novel fragmentation-function framework that allows one to connect a flavor definition in the deep UV, where partons live, to an IR definition, where jets live. The IR definition involves the Winner-Take-All axis and it has the advantage that the resulting evolution equations are linear. On the other hand, we consider the issue of interfacing measurements involving flavored jets (typically heavy-flavors) with precision calculations in QCD. We introduce a jet-flavor algorithm, based on Soft Drop grooming, which is at the same time IRC safe through NNLO and easy to implement in experimental analyses.
