### Chapter 2: Higgs and EW Symmetry Breaking Studies

R. Contino Et Al.
This Chapter summarises the physics opportunities for the study of Higgs bosons and the dynamics of electroweak symmetry breaking at the 100 TeV pp collider.

### Chapter 4: Heavy Ions at the Future Circular Collider

A. Dainese Et Al.
The Future Circular Collider (FCC) Study is aimed at assessing the physics potential and the technical feasibility of a new collider with centre-of-mass energies, in the hadron–hadron collision mode, seven times larger than the nominal LHC energies. Operating such machine with heavy ions is an option that is being considered in the accelerator design studies. It would provide, for example, Pb–Pb and p–Pb collisions at √sNN = 39 and 63 TeV, respectively, per nucleon–nucleon collision,...

Edited by: M. Aicheler, P.N. Burrows, N. Catalan, R. Corsini, M. Draper, J. Osborne,D. Schulte, S. Stapnes and M.J. 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...

### CERN Yellow Reports: Monographs, Vol. 4 (2020): LHC fixed target experiments: Report from the LHC Fixed Target Working Group of the CERN Physics Beyond Colliders Forum

Corresponding editor: Stefano.Redaelli@cern.ch Several fixed-target experiments at the LHC are being proposed and actively studied. Splitting of beam halo from the core by means of a bent crystal combined with a second bent crystal after the target has been suggested in order to study magnetic and electric dipole moments of short-lived particles. A similar scheme without the second crystal or other schemes with more conventional solid or gas targets have been proposed to study hadronic...

### Precision quantum chromodynamics

D. D’Enterria
The unprecedentedly small experimental uncertainties expected in the electron–positron mea- surements at the FCC-ee, key to searches for physics beyond the SM up to Λ ≈ 50 TeV, impose precise calculations for the corresponding theoretical observables. At the level of theoretical pre- cision required to match that of the FCC-ee experimental measurements, the current relevant QCD uncertainties have to be reduced at at least four different levels.

### Inclusion of mixed QCD–QED resummation effects at higher orders

G.F.R. Sborlini
In this section, we review some recent results concerning the inclusion of mixed QCD–QED corrections in the computation of physical observables. First, we comment on the extension of the Dokshitzer–Gribov–Lipatov–Altarelli–Parisi (DGLAP) equations to deal with the presence of mixed QCD–QED interactions. We describe the calculation of the full set of higher-order corrections to the splitting kernels, through the Abelianization algorithm. This procedure al- lows us to build the functional form of the QCD–QED corrections, starting...

J.J. Aguilera-Verdugo, F. Driencourt-Mangin, J. Plenter, S. Ramírez-Uribe, G. Rodrigo, G.F.R. Sborlini, W.J. Torres Bobadilla & S. Tracz
Computations in perturbative quantum field theory (pQFT) feature several aspects that, although intrinsically non-physical, are traditionally successfully eluded by modifying the dimen- sions of space–time. Closed loops in pQFT implicitly extrapolate the validity of the Standard Model (SM) to infinite energies—equivalent to zero distance—much above the Planck scale. We should expect this to be a legitimate procedure if the loop scattering amplitudes that contribute to the physical observables are either suppressed at very high energies,...

### Cold powering of the superconducting circuits

A. Ballarino, P. Cruikshank, J. Fleiter, Y. Leclercq, V. Parma & Y. Yang
For the HL-LHC project, a novel concept for the cold powering of superconducting magnets has been developed. It is based on a new type of superconducting lines (hereafter referred to as Superconducting (SC) Links) that have been developed to transfer the current to the new HL-LHC insertion region magnets from remote distances. Power converters and current leads will in fact be located in the new underground areas (UR) excavated for the HL-LHC (technical galleries running...

### 11 T dipole and new connection cryostat for the dispersion suppressor collimators

F. Savary & D. Schörling
In Run 3 the intensity of the ion beams (usually Pb ions) for ion–ion collisions is planned to be increased by a factor of three: from 40 × 109 to 120 × 109 circulating particles. This intensity increase will amplify the losses in the cold zone at P2 and P7 and may drive the beam induced heat losses in the main dipoles in the dispersion suppressor (DS) region above the quench limit. To avoid limiting...

### Cryogenics for the HL-LHC

S. Claudet, G. Ferlin, E. Monneret, A. Perin, O. Pirotte, M. Sisti & R. Van Weelderen
The upgrade of the cryogenics for the HL-LHC will consist of the following: • - The design and installation of two new cryogenic plants at P1 and P5 for high luminosity insertions. This upgrade will be based on a new sectorization scheme aimed at separating the cooling of the magnets in these insertion regions from the arc magnets and considering the newt feedboxes and superconducting links located in underground infrastructures. • - The design and...

### 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...
