We study the logarithmic accuracy of angular-ordered parton showers by considering the singular limits of multiple emission matrix elements. This allows us to consider different choices for the evolution variable and propose a new choice which has both the correct logarithmic behaviour and improved performance away from the singular regions. In particular the description of $e^+e^-$ event shapes in the non-logarithmic region is significantly improved.

    PanScales final-state showers now include quark masses at NLL accuracy while keeping original accuracy for massless observables.

  2. Studying the Infrared Behaviour of Improved Logarithmic Accuracy Parton Showers with Herwig

    hep-ph 2026-05 unverdicted novelty 5.0

    Implementing improved logarithmic accuracy parton showers in Herwig reveals that differences in infrared cutoffs have important effects on hadron-level predictions and tunability.

    Implementation of two NLL-accurate dipole showers in Herwig shows that differences in infrared cutoffs produce noticeable effects at the hadron level and affect model tunability.
