Reweighting underlying event and colour reconnection parameter variations in Sherpa

Journal of High Energy Physics
We propose and validate a new method to trace the impact of parameter variations in the simulation of multi-parton interactions and colour reconnections in the Sherpa event generator.

Studying the infrared behaviour of improved logarithmic accuracy parton showers with Herwig

Journal of High Energy Physics
We have implemented two recently proposed dipole shower algorithms that have next-to-leading-logarithmic accuracy at leading colour in the Herwig event generator.

The KrkNLO Method for Parton Shower Matching

Acta Physica Polonica B Proceedings Supplement
The consistent combination of Next-to-Leading-Order (NLO) perturbative QCD with the logarithmic resummation provided by parton shower algorithms (‘NLO matching’) is an indispensable tool for LHC phenomenology. Two methods for achieving this have been widely adopted: Mc@Nlo and Powheg. We summarise a third method, KrkNLO, its implementation in Herwig 7,

An algorithm to parallelise parton showers on a GPU

SciPost Physics Codebases
The Single Instruction, Multiple Thread (SIMT) paradigm of GPU programming does not support the branching nature of a parton shower algorithm by definition. However, modern GPUs are designed to schedule threads with diverging processes independently, allowing them to handle such branches.

Resonance- and width-aware parton shower evolution and NLO matching

Journal of High Energy Physics
We introduce a technique for the next-to-leading order accurate simulation of $${e}^{+}{e}^{-}\to {W}^{+}{W}^{-}b\overline{b }$$ that respects the resonant nature of the process above and near the top-quark pair production threshold.
