Description
The measurement of quark- and gluon-jet properties requires the determination of their fractions in experimental jet samples. This is commonly achieved by fitting data with quark- and gluon-jet templates derived from Monte Carlo simulations. Because the template shapes depend on the underlying model, the extracted jet fractions are intrinsically model-dependent. This talk reviews the main sources of model uncertainty in gluon-jet fraction measurements, their impact on the results, and methods for their evaluation in LHC data analyses.
