Contribution

It provides a detailed comparison of hadronization corrections across models and assesses their compatibility with NLO predictions in deep-inelastic scattering.

Findings

Hadronization corrections vary with jet definitions.

The k_perp algorithm has the smallest corrections.

Uncertainties in corrections are comparable to perturbative uncertainties.

Abstract

The size of non-perturbative corrections to high E_T jet production in deep-inelastic scattering is reviewed. Based on predictions from fragmentation models, hadronization corrections for different jet definitions are compared and the model dependence as well as the dependence on model parameters is investigated. To test whether these hadronization corrections can be applied to next-to-leading order (NLO) calculations, jet properties and topologies in different parton cascade models are compared to those in NLO. The size of the uncertainties in estimating the hadronization corrections is compared to the uncertainties of perturbative predictions. It is shown that for the inclusive k_\perp ordered jet clustering algorithm the hadronization corrections are smallest and their uncertainties are of the same size as the uncertainties of perturbative NLO predictions.
