FCC-ee and the CR effects [PDF]
EPJ Web of Conferences, 2019 The proposed new FCC-ee e+e– colliders will be hosted in the Geneva area as the new 100 km tunnel will allow producing collisions at centre-of-mass energies from 90 to 350 GeV and beyond at several interaction points and will be used for a precision ...

Particle identification at FCC-ee [PDF]
The European Physical Journal Plus, 2021 AbstractEquipping an experiment at FCC-ee with particle identification (PID) capabilities, in particular the ability to distinguish between hadron species, would bring great benefits to the physics programme. Good PID is essential for precise studies in quark flavour physics and is also a great asset for many measurements in tau, top, and Higgs physics.

High energy bremsstrahlung at the FCC-ee, FCC-eh and LHeC
European Physical Journal C: Particles and Fields, 2023 Bremsstrahlung spectra will be strongly distorted due to small lateral beam sizes at future colliders. That in turn will have large consequences for the electron and positron beam lifetimes as well as for the luminosity measurements in the case of ...

Search for the dipole portal of heavy neutral leptons at future colliders
Journal of High Energy Physics, 2023 In this paper, we study the potential of future colliders to explore the parameter space of heavy neutral leptons (HNLs) through the dipole portal. We consider hadron colliders such as the LHC in the high luminosity phase and FCC-hh, and lepton colliders,

Heavy neutrino-antineutrino oscillations at the FCC-ee
Journal of High Energy Physics, 2023 We discuss the impact of heavy neutrino-antineutrino oscillations ( N N ¯ Os $$ \textrm{N}\overline{\textrm{N}}\textrm{Os} $$ ) on heavy neutral lepton (HNL) searches at proposed electron-positron colliders such as the future circular e + e − collider ...

Mechanical model for the FCC-ee interaction region
EPJ Techniques and Instrumentation, 2023 The Future Circular Collider FCC-ee aims at unprecedented luminosities to be obtained with the crab-waist collision scheme. In this paper we describe the mechanical model of the interaction region layout including its assembly procedure.

Impedance modelling and collective effects in the Future Circular e+e− Collider with 4 IPs
EPJ Techniques and Instrumentation, 2022 The FCC-ee impedance model is being constantly updated closely following the vacuum chamber design and parameters evolution. In particular, at present, a thicker NEG coating of 150 nm (instead of previous 100 nm) has been suggested by the vacuum experts,

Searches for long-lived particles at the future FCC-ee
Frontiers in Physics, 2022 The electron-positron stage of the Future Circular Collider, FCC-ee, is a frontier factory for Higgs, top, electroweak, and flavour physics. It is designed to operate in a 100 km circular tunnel built at CERN, and will serve as the first step towards ...

Direct measurement of alpha_QED(mZ) at the FCC-ee [PDF]
, 2015 When the measurements from the FCC-ee become available, an improved determination of the standard-model "input" parameters will be needed to fully exploit the new precision data towards either constraining or fitting the parameters of beyond-the-standard-

Spin resonance canceling lattice cell design principles
Physical Review Accelerators and Beams, 2023 We show how to construct an accelerator lattice cell that minimizes all intrinsic spin resonances. We then apply this approach to various toy electron and proton accelerators, considering, AGS-booster, AGS-like and CEPC/FCC-ee, and FCC-hh-like rings.
