(i.e. flavored jet algorithms) * Tests of quark/gluon taggers? (ATLAS/CMS/theory) * Why do current parton showers give such large discrepancies in quark/gluon tagging performances? * Data available to tune quark/gluon taggers? (RIVETized analyses?) * Key future measurements to be made? (at LHC or even in archival data?) * Quark/gluon enriched samples? (e.g. dijet vs. gamma/W/Z + jet) * Can NnLO/NnLL calculations improve our understanding? * Impact of soft QCD (underlying event) and pileup? == Higgs properties and modelling == * How to improve and make best use of differential cross section measurements? == Off-Shell Higgs == == ME-PS matching and multileg merging == * Parton shower systematics * Multijet merging systematics * Tuning in presence of matching + merging * Matching with photons and QED corrections * cross generator comparison, possibly ttbar+jets (other channels welcome) ===== Interface SM/BSM ===== == Presentation of LHC results == * Intimately related to this is the issue of fiducial cross sections.
