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

Jack Holguin, Michael H. Seymour, Siddharth Sule, Simon Pl\"atzer

Parton showers with improved logarithmic accuracy still produce different hadron-level results because of how they set their infrared cutoffs.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Studying the results at the hadron level, we find important consequences of this infrared cutoff difference and propose it as a starting point for further study of the interplay between parton showers and hadronization models.

C2weakest assumption

That the observed differences at hadron level are primarily driven by the precise definition of the infrared cutoff used by each shower rather than by other modeling choices in the NLO matching or cluster hadronization.

C3one line summary

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