Stuart Abstract: The Compact Linear Collider (CLIC) is a TeV-scale high-luminosity linear e + e − collider under development by international collaborations hosted by CERN. This document provides an overview of the design, technology, and implementation aspects of the CLIC accelerator. For an optimal exploitation of its physics potential, CLIC is foreseen to be built and...

Standard Model physics at the HL-LHC and HE-LHC

Editors: P. Azzi, S. Farry, P. Nason & A. Tricoli
The successful operation of the Large Hadron Collider (LHC) and the excellent performance of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with $pp$ collisions at center-of-mass energies of 7, 8 and 13 TeV as well as the giant leap in precision calculations and modeling of fundamental interactions at hadron colliders have allowed an extraordinary breadth of physics studies including precision measurements of a variety physics processes. The LHC results have so...

Opportunities in flavour physics at the HL-LHC and HE-LHC

Ediotors: A. Cerri, V. V. Gligorov, S. Malvezzi, J. Martin Camalich & J. Zupan
Motivated by the success of the flavour physics programme carried out over the last decade at the Large Hadron Collider (LHC), we characterize in detail the physics potential of its High-Luminosity and High-Energy upgrades in this domain of physics. We document the extraordinary breadth of the HL/HE-LHC programme enabled by a putative Upgrade II of the dedicated flavour physics experiment LHCb and the evolution of the established flavour physics role of the ATLAS and CMS...

Beamline – main components

B. Carlsen, F. Carvalho, V. De Jesus, J. De La Gama, A. Ebn Rahmoun, R. Froeschl, M. Gourber-Pace, E. Grenier Boley, R. Lopez, R. Mompo, K. Papastergiou, G. Romagnoli, J. Tan & L. Wilhelm
The East Area renovation will cover the refurbishment of the East Hall with its beamlines and infrastructures. A re-design of the beamlines is included to improve the magnet situation, the radiation situation, and maintainability in general. Thanks to a cycled powering mode of the magnets instead of a steady state one, considerable energy savings will be possible. Therefore, several magnet families have to be re-designed to be in accordance with the purposes of the project....

Introduction, scope, and schedule

J. Bernhard, S. Evrard & E. Harrouch
The East Area of the CERN Proton Synchrotron has served the physics community for over 50 years and remains extremely popular and necessary, among other things, to complete full calibration over a large energy spectrum of the detectors to be installed in the Large Hadron Collider (LHC) experiments according to the needs of the upgrade for the High Luminosity LHC. In addition, physics programs like CLOUD, and test facilities such as IRRAD and CHARM are...

Introduction

D. Newbold
The 2020 update of the European Strategy for Particle Physics Update (ESPPU) outlined the current status and prospects in the field, and identified priorities for future particle physics accelerator facilities. In time order, these are: completion and commissioning of the CERN High Luminosity LHC (HL-LHC); a future electron-positron Higgs factory; and a future hadron collider at the highest achievable energy and luminosity.

Energy-recovery linacs

M. Klein, A. Hutton, D. Angal-Kalinin, K. Aulenbacher, A. Bogacz, G. Hoffstaetter, E. Jensen, W. Kaabi, D. Kayran, J. Knobloch, B. Kuske, F. Marhauser, N. Pietralla, O. Tanaka, C. Vaccarezza, N. Vinokurov, P. Williams & F. Zimmermann
Energy Recovery is at the threshold of becoming a key means for the advancement of accelerators. Recycling the kinetic energy of a used beam for accelerating a newly injected beam, i.e. reducing the power consumption, utilising the high injector brightness and dumping at injection energy: these are the key elements of a novel accelerator concept, invented half a century ago. The potential of this technique may be compared with the finest innovations of accelerator technology...

Novel high-gradient accelerators have demonstrated acceleration of electrons and positrons with electric field strengths of 1 to > 100 GeV/m. This is about 10 to 1000 times higher than achieved in RF-based accelerators, and as such they have the potential to overcome the limitations associated with RF cavities. Plasma-based accelerators have produced multi-GeV bunches with parameters approaching those suitable for a linear collider. A significant reduction in size and, perhaps, cost of future accelerators can...

Chapter 5: Physics Opportunities with the FCC-hh Injectors

B. Goddard Et Al.
In this chapter we explore a few examples of physics opportunities using the existing chain of accelerators at CERN, including potential upgrades. In this context the LHC ring is also considered as a part of the injector system. The objective is to find examples that constitute sensitive probes of New Physics that ideally cannot be done elsewhere or can be done significantly better at the CERN accelerator complex. Some of these physics opportunities may require...

Prospects for higher-order corrections to W pair production near threshold in the EFT approach

C. Schwinn
The precise measurement of the mass of the W boson plays an essential role for precision tests of the Standard Model (SM) and indirect searches for new physics through global fits to electroweak observables. Cross-section measurements near the W pair production threshold at a possible future e−e+ collider promise to reduce the experimental uncertainty to the level of 3 MeV at an International Linear Collider (ILC), while a high-luminosity circular collider offers a potential improvement...

Vertex functions in QCD—preparation for beyond two loops

J.A. Gracey
We summarise the algorithm to determine the two-loop off-shell three-point vertex functions of QCD before outlining the steps required to extend the results to three and more loops.

Effective field theory approach to QED corrections in flavour physics

M. Beneke, C. Bobeth & R. Szafron
Thanks to the accurate measurements performed at the low-energy facilities and the LHC, flavour physics of light quarks, especially the bottom quark, emerged on the precision frontier for tests of the Standard Model (SM) and in searches for new physics effects. On the theoretical side, short-distance perturbative higher-order QCD and electroweak corrections are under good control for many processes. Moreover, tremendous progress in lattice computations allows percentage to even subpercentage accuracy to be achieved for...

Numerics for elliptic Feynman integrals

C. Bogner, I. Hönemann, K. Tempest, A. Schweitzer & S. Weinzierl
The Standard Model involves several heavy particles: the Z and W bosons, the Higgs boson, and the top quark. Precision studies of these particles require, on the theoretical side, quantum corrections at the two-loop order and beyond. It is a well-known fact that, starting from two loops, Feynman integrals with massive particles can no longer be expressed in terms of multiple polylogarithms. This immediately raises the following question. What is the larger class of functions...

CERN Yellow Reports: Monographs, Vol. 10 (2020): High-Luminosity Large Hadron Collider (HL-LHC): Technical design report

Editors: I. Béjar Alonso, O. Brüning, P. Fessia, M. Lamont, L. Rossi, L. Tavian, M. Zerlauth The Large Hadron Collider (LHC) is one of the largest scientific instruments ever built. Since opening up a new energy frontier for exploration in 2010, it has gathered a global user community of about 9000 scientists working in fundamental particle physics and the physics of hadronic matter at extreme temperature and density. To sustain and extend its discovery potential,...

O. Brüning & L. Rossi
The Large Hadron Collider (LHC) was successfully commissioned in 2010 for proton–proton collisions with a 7 TeV centre-of-mass (c.o.m.) energy. It delivered 8 TeV c.o.m. proton collisions from April 2012 until the end of Run 1 in 2013. Following the Long Shutdown 1 (LS1) in 2013–2014, it operated with 13 TeV c.o.m. proton collisions during Run 2 from 2015 until the end of 2018, reaching a peak luminosity twice the nominal design value. At present...
