Disentangling Heavy Flavor at Colliders

Understand

We propose two new analysis strategies for studying charm and beauty quarks at colliders.

• The first strategy is aimed at testing the kinematics of heavy-flavor quarks within an identified jet.
• Here, we use the SoftDrop jet-declustering algorithm to identify two subjets within a large-radius jet, using subjet flavor tagging to test the heavy-quark splitting functions of QCD.
• For subjets containing a $J / \psi$ or $\Upsilon$, this declustering technique can also help probe the mechanism for quarkonium production.
