Understand

We perform a detailed study of the sources of perturbative uncertainty in parton shower predictions within the Herwig 7 event generator.

We benchmark two rather different parton shower algorithms, based on angular-ordered and dipole-type evolution, against each other.
We deliberately choose leading order plus parton shower as the benchmark setting to identify a controllable set of uncertainties.
This will enable us to reliably assess improvements by higher-order contributions in a follow-up work.
