The possibility to reanalyse data taken by the HERA experiments offers thechance to study modern QCD jet and event-shape observables in deep-inelasticscattering. To address this, we compute resummed and matched predictions forthe 1-jettiness distribution in neutral current DIS with and without groomingthe hadronic final state using the soft-drop technique. Our theoreticalpredictions also account for non-perturbative corrections from hadronisationthrough parton-to-hadron level transfer matrices extracted from dedicated MonteCarlo simulations with Sherpa. To estimate parameter uncertainties inparticular for the beam-fragmentation modelling we derive a family of replicatunes to data from the HERA experiments. While NNLO QCD normalisationcorrections to the NLO+NLL' prediction are numerically small, hadronisationcorrections turn out to be quite sizeable. However, soft-drop groomingsignificantly reduces the impact of non-perturbative contributions. Wesupplement our study with hadron-level predictions from Sherpa based on thematching of NLO QCD matrix elements with the parton shower. Good agreementbetween the predictions from the two calculational methods is observed.
