European Physical Journal C: Particles and Fields, 2020 A new release of the Monte Carlo event generator Herwig (version 7.2) is now available. This version introduces a number of improvements over the major version 7.0, notably: multi-jet merging with the dipole shower at LO and NLO QCD; spin correlations in

NNLOPS description of the H→ b b ¯ $$ b\overline{b} $$ decay with MiNLO
Journal of High Energy Physics, 2020 We present an event generator that describes the Higgs boson decay into b-quarks at next-to-next-to-leading-order (NNLO) in QCD and allows for a consistent matching to parton shower.

Hadronic decays of Higgs boson at NNLO matched with parton shower
Journal of High Energy Physics, 2021 We present predictions for hadronic decays of the Higgs boson at next-to-next-to-leading order (NNLO) in QCD matched with parton shower based on the POWHEG framework.

Momentum conservation and unitarity in parton showers and NLL resummation
Journal of High Energy Physics, 2018 We present a systematic study of differences between NLL resummation and parton showers. We first construct a Markovian Monte-Carlo algorithm for resummation of additive observables in electron-positron annihilation.

PanScales parton showers for hadron collisions: formulation and fixed-order studies
Journal of High Energy Physics, 2022 We formulate PanScales parton showers for hadron collisions so as to achieve next-to-leading logarithmic (NLL) accuracy across a broad set of observables. We do so specifically for colour singlet production. Relative to the existing PanScales final-state

Associated production of charged Higgs bosons and top quarks with POWHEG [PDF]
, 2012 The associated production of charged Higgs bosons and top quarks at hadron colliders is an important discovery channel to establish the existence of a non-minimal Higgs sector. Here, we present details of a next-to-leading order (NLO) calculation of this

NLO corrections in the initial-state parton shower Monte Carlo [PDF]
, 2013 The decade-old technique of combining NLO-corrected hard process with LO-level parton shower Monte Carlo is now mature and used in practice of the QCD calculations in the LHC data analysis.

A new approach to color-coherent parton evolution
Journal of High Energy Physics, 2023 We present a simple parton-shower model that replaces the explicit angular ordering of the coherent branching formalism with a differentially accurate simulation of soft-gluon radiation by means of a non-trivial dependence of the splitting functions on ...

Top quark pair production in association with a jet with NLO parton showering [PDF]
, 2011 We compute the production cross section of a top-antitop pair in association with a jet at hadron colliders at next-to-leading order accuracy matched with parton shower algorithms to make predictions at the hadron level.

Drell-Yan Production Using a New Approach PDF2ISR in the PYTHIA Event Generator [PDF]
EPJ Web of ConferencesWe present PDF2ISR, a new method for constructing an initial partem shower consistent with parton densities, applied to Drell-Yan production. Implemented in the PYTHIA8 event generator, it incorporates the Parton Branching framework to modify the initial-
