Contribution
It presents a novel antenna shower algorithm with on-the-fly uncertainty estimation, improving simulation precision for hadron collider physics.
Findings
Incorporates iterated matrix-element corrections.
Provides automated perturbative uncertainty estimates.
Available as a PYTHIA 8 plug-in.
Abstract
We summarise the main features of VINCIA's antenna-based treatment of QCD initial- and final-state showers, which includes iterated tree-level matrix-element corrections and automated evaluations of perturbative shower uncertainties. The latter are computed on the fly and are cast as a set of alternative weights for each generated event. The resulting algorithm has been made publicly available as a plug-in to the PYTHIA 8 event generator.
