We review the main software and computing challenges for the Monte Carlo physics event generators used by the LHC experiments, in view of the High-Luminosity LHC (HL-LHC) physics programme. This paper has been prepared by the HEP Software Foundation (HSF) Physics Event Generator Working Group as an input to the LHCC review of HL-LHC computing, which has started in May 2020. 
Accelerating LHC phenomenology with analytic one-loop amplitudes
The evaluation of one-loop matrix elements is one of the main bottlenecks in precision calculations for the high-luminosity phase of the Large Hadron Collider. To alleviate this problem, a new C++
Modelling and computational improvements to the simulation of single vector-boson plus jet processes for the ATLAS experiment
This paper presents updated Monte Carlo configurations used to model the production of single electroweak vector bosons (W , Z/γ∗) in association with jets in proton–proton collisions for the ATLAS
HL-LHC Computing Review: Common Tools and Community Software
This document addresses the issues for software that is used in multiple experiments and maintained by teams of developers who are either not linked to a particular experiment or who contribute to common software within the context of their experiment activity.
Many-gluon tree amplitudes on modern GPUs: A case study for novel event generators
The performance of various recursive strategies to compute multi-gluon tree-level amplitudes and the scaling of the algorithms on both CPU and GPU hardware is investigated.
Reducing negative weights in Monte Carlo event generation with Sherpa
An increase in theoretical precision of Monte Carlo event generators is typically accompanied by an increased need for computational resources. One major obstacle are negative weighted events, which
HEP computing collaborations for the challenges of the next decade
The strategy by which the international HEP computing infrastructure, software and services should evolve through the collaboration of large and smaller scale HEP experiments, while respecting the specific needs of each community is outlined.
Design and engineering of a simplified workflow execution for the MG5aMC event generator on GPUs and vector CPUs
This paper describes an ongoing activity to reengineer the Madgraph5_aMC@NLO physics event generator, primarily to port it and allow its efficient execution on GPUs, but also to modernize it and optimize its performance on vector CPUs.
The HEP Software Foundation Community
The motivation for the founding of the organisation is outlined and how the organisation functions today and what challenges remain to be faced in the future are described.

Simulation of vector boson plus many jet final states at the high luminosity LHC
We present a novel event generation framework for the efficient simulation of vector boson plus multi-jet backgrounds at the high-luminosity LHC and at possible future hadron colliders. MPI
Systematic event generator tuning for the LHC
In this article we describe Professor, a new program for tuning model parameters of Monte Carlo event generators to experimental data by parameterising the per-bin generator response to parameter
The LHCb detector at the LHC
The LHCb experiment is dedicated to precision measurements of CP violation and rare decays of B hadrons at the Large Hadron Collider (LHC) at CERN (Geneva). The initial configuration and expected
Event generation with Sherpa 2.2
This work summarises essential features and improvements of the Sherpa 2.2 release series, which is heavily used for event generation in the analysis and interpretation of LHC Run 1 and Run 2 data.

A method that allows to consistently re-use parton-level samples accurate up to NLO in QCD under different theoretical hypotheses is described and its validation is shown by applying it to several cases of practical interest for the search of new physics at the LHC.
Monte Carlo event generators for high energy particle physics event simulation
Monte Carlo event generators (MCEGs) are the indispensable workhorses of particle physics, bridging the gap between theoretical ideas and first-principles calculations on the one hand, and the
QCD Radiation in the Production of Heavy Colored Particles at the LHC
We present a study of the effects of QCD radiation in the production of heavy colored states, employing inclusive multi-jet samples obtained by matching matrix elements and parton showers. We discuss
The ALICE experiment at the CERN LHC
ALICE (A Large Ion Collider Experiment) is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model. It is designed to address
