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 ...

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 ...

Photon splitting corrections to soft-photon resummation

Journal of High Energy Physics, 2023
In this paper we present an algorithm to add photon-splitting corrections to the Yennie-Frautschi-Suura-style soft-photon resummation available in the Sherpa MonteCarlo event generator.

Drell-Yan Production at NNLL'+NNLO Matched to Parton Showers

, 2015
We present results for Drell-Yan production from the GENEVA Monte-Carlo framework. We combine the fully-differential NNLO calculation with higher-order resummation in the 0-jettiness resolution variable.

Jet quenching within a hybrid strong/weak coupling approach

, 2014
We propose a novel hybrid model for jet quenching, including both strong and weak coupling physics where each seems appropriate. Branching in the parton shower is assumed to be perturbative and described by DGLAP evolution, while interactions with the ...

Squark Production and Decay matched with Parton Showers at NLO [PDF]

, 2014
Extending previous work on the predictions for the production of supersymmetric (SUSY) particles at the LHC, we present the fully differential calculation of the next-to-leading order (NLO) SUSY-QCD corrections to the production of squark and squark ...

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 ...

Combining states without scale hierarchies with ordered parton showers

, 2017
We present a parameter-free scheme to combine fixed-order multi-jet results with parton-shower evolution. The scheme produces jet cross sections with leading-order accuracy in the complete phase space of multiple emissions, resumming large logarithms ...

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.
