Polarized Deep-Inelastic Scattering with Spin Correlations in Herwig 7

M. R. Masouminia, A. Papaefstathiou, P. Richardson

We investigate polarized deep-inelastic scattering (DIS) in the context of fully exclusive Monte Carlo simulations for the Electron-Ion Collider (EIC). We present a next-to-leading…

Searching for New Physics Inside Jets with the Herwig 7 Generalised Parton Shower

Taehee Kim, Joon-Bin Lee, M. R. Masouminia +2

This study investigates parton shower evolution incorporating both Standard Model (SM) and beyond-the-Standard-Model (BSM) radiation, focusing on the phenomenology of a massive $Z'…

Gauge-Invariant Longitudinal Modes in the Herwig 7 Electroweak Parton Shower

M. R. Masouminia, P. Richardson

Longitudinal electroweak gauge bosons are the most technically delicate ingredient of electroweak parton showers: in the broken Standard Model, the gauge component of a longitudina…

The Physics of Herwig 7

J. Bellm, G. Bewick, S. Ferrario Ravasio +23

We present the physics foundations and recent developments of Herwig 7, the modern successor of the original HERWIG and Herwig++ series. Herwig 7 provides a flexible and systematic…

Quarkonium Parton Shower in Herwig 7

M. R. Masouminia, P. Richardson

We present the implementation of a fully automated quarkonium parton shower in Herwig 7, based on non-relativistic QCD (NRQCD) factorisation with spin-colour projections. The frame…

Event Generators for High-Energy Physics Experiments

J. M. Campbell, M. Diefenthaler, T. J. Hobbs +221

We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of acti…
