What is a parton shower? [PDF]
, 2017 We consider idealized parton shower event generators that treat parton spin and color exactly, leaving aside the choice of practical approximations for spin and color.

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.

Parton-shower matching systematics in vector-boson-fusion WW production
European Physical Journal C: Particles and Fields, 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 ...

An analytic initial-state parton shower [PDF]
Journal of High Energy Physics, 2012 Abstract We present a new algorithm for an analytic parton shower. While the algorithm for the final-state shower has been known in the literature, the construction of an initialstate shower along these lines is new. The aim is to have a parton shower algorithm for which the full analytic form of the probability distribution for ...

Reweighting a parton shower using a neural network: the final-state case
Journal of High Energy Physics, 2019 The use of QCD calculations that include the resummation of soft-collinear logarithms via parton-shower algorithms is currently not possible in PDF fits due to the high computational cost of evaluating observables for each variation of the PDFs ...

Gaining analytic control of parton showers [PDF]
Physical Review D, 2007 Parton showers are widely used to generate fully exclusive final states needed to compare theoretical models to experimental observations. While, in general, parton showers give a good description of the experimental data, the precise functional form of ...

Implementing NLO DGLAP evolution in parton showers [PDF]
Journal of High Energy Physics, 2017 We present a parton shower which implements the DGLAP evolution of parton densities and fragmentation functions at next-to-leading order precision up to effects stemming from local four-momentum conservation.

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 automated computation of tree-level and next-to-leading order differential cross sections, and their matching to parton shower simulations [PDF]
Journal of High Energy Physics, 2014 We discuss the theoretical bases that underpin the automation of the computations of tree-level and next-to-leading order cross sections, of their matching to parton shower simulations, and of the merging of matched samples that differ by light-parton ...
