2. Towards the universal jet algorithm to disentangle heavy flavor at hadron colliders?

First morning session: Heavy Flavor

Towards the universal jet algorithm to disentangle heavy flavor at hadron colliders (for X to bb tagging for arbitrary pT(X), and for optimally distinguishing single from g—>bb jets). The talk includes discussion of dependence on heavy flavor modeling (production/decays), and on how to label heavy flavor correctly in the context of each jet algorithm.
