Anatomy of LHC Collisions - And Future Challenges
/ Skands, Peter (speaker) (Monash University (AU))
I will give an overview of our current picture of the physical mechanisms that are at play in LHC collisions, and review the current state of the art of detailed numerical models of these processes. I will explain why I believe we are on the cusp of at least two exciting revolutions, and outline some of the main challenges in realising them. [...]

QCD challenges from pp to AA collisions: 4th edition
/ Altmann, Javira (Monash U.) ; Andres, Carlota (Ecole Polytechnique, CPHT) ; Andronic, Anton (Munster U., ITP) ; Antinori, Federico (INFN, Padua) ; Antonioli, Pietro (INFN, Bologna ; Bologna U.) ; Beraudo, Andrea (INFN, Turin) ; Berti, Eugenio (INFN, Florence) ; Bianchi, Livio (INFN, Turin ; Turin U.) ; Boettcher, Thomas (Cincinnati U.) ; Capriotti, Lorenzo (Ferrara U.) et al.
This paper is a write-up of the ideas that were presented, developed and discussed at the fourth International Workshop on QCD Challenges from pp to AA, which took place in February 2023 in Padua, Italy. The goal of the workshop was to focus on some of the open questions in the field of high-energy heavy-ion physics and to stimulate the formulation of concrete suggestions for making progresses on both the experimental and theoretical sides.

A standard convention for particle-level Monte Carlo event-variation weights
/ Bothmann, Enrico (Gottingen U.) ; Buckley, Andy (Glasgow U.) ; Gütschow, Christian (University Coll. London) ; Prestel, Stefan (Lund U.) ; Schönherr, Marek (Durham U., IPPP) ; Skands, Peter (Monash U.) ; Andersen, Jeppe R. (Durham U., IPPP) ; Bhattacharya, Saptaparna (Northwestern U.) ; Butterworth, Jonathan Mark (University Coll. London) ; Chahal, Gurpreet Singh (Durham U., IPPP) et al.
Streams of event weights in particle-level Monte Carlo event generators are a convenient and immensely CPU-efficient approach to express systematic uncertainties in phenomenology calculations, providing systematic variations on the nominal prediction within a single event sample. But the lack of a common standard for labelling these variation streams across different tools has proven to be a major limitation for event-processing tools and analysers alike. [...]

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 complex detector signatures and data of the experimental community on the other hand. [...]

LHC@Home: a BOINC-based volunteer computing infrastructure for physics studies at CERN
/ Barranco, Javier (Ecole Polytechnique, Lausanne, LPAP) ; Cai, Yunhai (SLAC) ; Cameron, David (Oslo U.) ; Crouch, Matthew (CERN) ; De Maria, Riccardo (CERN) ; Field, Laurence (CERN) ; Giovannozzi, Massimo (CERN) ; Hermes, Pascal (CERN) ; Høimyr, Nils (CERN) ; Kaltchev, Dobrin (TRIUMF) et al.
The LHC@Home BOINC project has provided computing capacity for numerical simulations to researchers at CERN since 2004, and has since 2011 been expanded with a wider range of applications. The traditional CERN accelerator physics simulation code SixTrack enjoys continuing volunteers support, and thanks to virtualisation a number of applications from the LHC experiment collaborations and particle theory groups have joined the consolidated LHC@Home BOINC project.

Systematics of quark/gluon tagging
/ Gras, Philippe (IRFU, Saclay) ; Höche, Stefan (SLAC) ; Kar, Deepak (Witwatersrand U.) ; Larkoski, Andrew (Reed Coll.) ; Lönnblad, Leif (Lund U. ; Lund U., Dept. Theor.

By measuring the substructure of a jet, one can assign it a "quark" or "gluon" tag. In the eikonal (double-logarithmic) limit, quark/gluon discrimination is determined solely by the color factor of the initiating parton (C_F versus C_A). [...]

QCD and $\gamma\,\gamma$ studies at FCC-ee
/ Skands, Peter (Monash U.) ; d'Enterria, David (CERN)
The Future Circular Collider (FCC) is a post-LHC project aiming at searches for physics beyond the SM in a new 80--100~km tunnel at CERN. Running in its first phase as a very-high-luminosity electron-positron collider (FCC-ee), it will provide unique possibilities for indirect searches of new phenomena through high-precision tests of the SM.
