Double Higgs production at NNLO interfaced to parton showers in GENEVA

Journal of High Energy Physics, 2023
In this work, we study the production of Higgs boson pairs at next-to-next-to-leading order in QCD matched to parton showers, using the Geneva framework and working in the heavy-top-limit approximation.

Collinear and TMD distributions with dynamical soft-gluon resolution scale

Journal of High Energy Physics
Soft-gluon resolution scales characterize parton branching Monte Carlo implementations of the evolution equations for parton distribution functions in Quantum Chromodynamics (QCD).

Resonance-aware parton-shower matching for off-shell top–antitop production with semi-leptonic decays at electron–positron colliders

Journal of High Energy Physics
We present full off-shell NLO corrections in QCD obtained with the MoCaNLO code matched to parton shower. A resonance-aware matching procedure has been devised for the MC@NLO method tuned to the Catani-Seymour dipole subtraction.

Measurement of the production cross section of prompt J/ψ mesons in association with a W± boson in pp collisions at p s = 7 TeV with the ATLAS detector [PDF]

, 2014
The process pp → W±J/ψ provides a powerful probe of the production mechanism of charmonium in hadronic collisions, and is also sensitive to multiple parton interactions in the colliding protons.

CASCADE3 A Monte Carlo event generator based on TMDs

European Physical Journal C: Particles and Fields, 2021
The Cascade3 Monte Carlo event generator based on Transverse Momentum Dependent (TMD) parton densities is described. Hard processes which are generated in collinear factorization with LO multileg or NLO parton level generators are extended by adding ...

Logarithmic accuracy of parton showers: a fixed-order study

Journal of High Energy Physics, 2018
We formulate some first fundamental elements of an approach for assessing the logarithmic accuracy of parton-shower algorithms based on two broad criteria: their ability to reproduce the singularity structure of multi-parton matrix elements, and their ...

A partitioned dipole-antenna shower with improved transverse recoil

Journal of High Energy Physics
The implementation of a new final-state parton-shower algorithm in the Pythia event generator is described. The shower algorithm, dubbed Apollo, combines central aspects of the Vincia antenna shower with the global transverse-recoil scheme of the Alaric ...

Multi-jet production in deep inelastic scattering with Pythia

Journal of High Energy Physics
We introduce multi-jet merging for deep inelastic scattering in the Vincia parton shower in the Monte Carlo event generator Pythia 8. Merging combines event samples of different parton multiplicities with logarithmically enhanced parton-shower radiation.
