  "abstract": "We introduce a method for matching the neutral-current deep inelastic scattering process with parton showers in Pythia 8, at first order in the strong coupling. The implementation, based on the well-established multiplicative matching approach, is achieved by reweighting leading-order Born-level events and requires that the first parton-shower emission is distributed according to the real matrix-element. The method is implemented as an internal matching strategy in the Pythia 8 event generator applicable to both currently available parton-shower algorithms, the default one and Vincia. The validity of higher-order corrections is verified with comparisons against existing next-to-leading order simulations. The strategy is used to describe reduced cross-sections measured at the HERA collider, and we find better overall agreement and reduced uncertainties with the matching.",
