The Vincia parton shower [PDF]
Proceedings of XXI International Workshop on Deep-Inelastic Scattering and Related Subjects — PoS(DIS 2013), 2013 We summarize recent developments in the VINCIA parton shower. After a brief review of the basics of the formalism, the extension of VINCIA to hadron collisions is sketched. We then turn to improvements of the efficiency of tree-level matching by making the shower history unique and by incorporating identified helicities. We conclude with an overview of

Implementation of angularly ordered electroweak parton shower in Herwig 7 [PDF]
Journal of High Energy Physics, 2022 We discuss the necessary steps for implementing an angularly ordered (AO) electroweak (EW) parton shower in Herwig 7 multi-purpose event generator. This includes calculating the helicity-dependent quasi-collinear EW branching functions that correspond to

Spin correlations in parton shower simulations [PDF]
The European Physical Journal C, 2020 AbstractSpin correlations are an important, but often neglected, effect in modern Monte Carlo event generators. We show that they can be fully incorporated in Herwig7 using the algorithm originally proposed by Collins and Knowles in all stages of the event generation process and between the different stages of the event generation.

Parton shower and NLO-matching uncertainties in Higgs boson pair production
Journal of High Energy Physics, 2018 We perform a detailed study of NLO parton shower matching uncertainties in Higgs boson pair production through gluon fusion at the LHC based on a generic and process independent implementation of NLO subtraction and parton shower matching schemes for ...

Electroweak W+W+ production in association with three jets at NLO QCD matched with parton shower
Journal of High Energy PhysicsWe present a next-to-leading order QCD calculation for the electroweak production of a pair of same-sign weak gauge bosons in association with three jets in the region dominated by vector-boson scattering, and its matching with parton-shower programs ...

Explainable machine learning of the underlying physics of high-energy particle collisions
Physics Letters B, 2022 We present an implementation of an explainable and physics-aware machine learning model capable of inferring the underlying physics of high-energy particle collisions using the information encoded in the energy-momentum four-vectors of the final state ...

Probabilistic Neural Computing with Stochastic Devices
Advanced Materials, Volume 35, Issue 37, September 14, 2023., 2023 Modern computing assumes that materials, devices, and circuits will be operated in a fully deterministic manner, providing predictable and reliable outputs, with any desired random behavior re‐introduced in software. This perspective describes how the integration of tunable stochastic devices into neuromorphic computing architectures can allow future ...
