Deep learning as a parton shower [PDF]
Journal of High Energy Physics, 2018 We make the connection between certain deep learning architectures and the renormalisation group explicit in the context of QCD by using a deep learning network to construct a toy parton shower model.

The ALARIC parton shower [PDF]
EPJ Web of ConferencesParton showers are important tools in the event generation chain for present and future colliders. Recently, their formally achieved accuracy has been under extended scrutiny.

Parton-shower matching systematics in vector-boson-fusion WW production [PDF]
European Physical Journal C, 2017 We perform a detailed analysis of next-to-leading order plus parton-shower matching in vector-boson-fusion WW production including leptonic decays. The study is performed in the Herwig 7 framework interfaced to VBFNLO 3, using the angular-ordered and ...

A parton shower consistent with parton densities at LO and NLO: Pdf2Isr
European Physical Journal C: Particles and FieldsWe present a method for obtaining an initial-state parton shower model where the (backward) evolution fully consistent with the (forward) evolution of the collinear parton density used.

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 thebasics of the formalism, the extension of VINCIA to hadron collisions is sketched. We then turnto improvements of the efficiency of tree-level matching by making the

Building a consistent parton shower [PDF]
Journal of High Energy Physics, 2020 Modern parton showers are built using one of two models: dipole showers or angular ordered showers. Both have distinct strengths and weaknesses. Dipole showers correctly account for wide-angle, soft gluon emissions and track the leading flows in QCD ...

What is a parton shower? [PDF]
Physical Review D, 2017 We present a formulation for a parton shower at an arbitrary order of perturbation theory, with the aim of indicating how a parton shower can be understood as a systematically improvable approximation, similarly to ordinary perturbative calculations 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

A Parton Shower for High Energy Jets [PDF]
Journal of High Energy Physics, 2011 We present a method to match the multi-parton states generated by the High Energy Jets Monte Carlo with parton showers generated by the Ariadne program using the colour dipole model.

Calculations with off-shell matrix elements, TMD parton densities and TMD parton showers [PDF]
European Physical Journal C: Particles and Fields, 2018 A new calculation using off-shell matrix elements with TMD parton densities supplemented with a newly developed initial state TMD parton shower is described.
