  1. 1. Long-Lived Particles from exotic Higgs decays at the FCC-ee

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Magdalena Vande Voorde; [2023]
    Nyckelord :;

    Sammanfattning : This thesis presents the first sensitivity analysis for exotic Higgs boson decays at the electron-positron stage of the Future Circular Collider (FCC-ee) within the FCCAnalyses framework. The project studies the production of a Higgs boson in association with a Z boson in electron-positron collisions at a center-of-mass energy of 240 GeV, with the Higgs boson decaying into two long-lived scalars and the Z boson decaying leptonically.

  3. 2. Long-Lived Heavy Neutral Leptons at the FCC-ee

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Lovisa Rygaard; [2022]
    Nyckelord :;

    Sammanfattning : The Future Circular electron-positron Collider (FCC-ee) is a high luminosity frontier particle accelerator for high precision measurements of the heaviest fundamental particles and possible evidence of new physics. Heavy Neutral Leptons (HNLs) are examples of new particles with discovery potential at the FCC-ee that could answer some of the most substantial questions in particle physics, such as how neutrinos oscillate between flavour eigenstates.

  4. 3. Increasing the efficiency of the CERN accelerators by use of Superconducting Magnetic Energy Storage (SMES)

    Master-uppsats, Uppsala universitet/FREIA

    Författare :Joakim Kvarnström; [2021]
    Nyckelord :Energy Storage; Power Conversion; Particle Accelerator; Superconductivity; SMES;

    Sammanfattning : This report explains how an SMES is operated and how SMES systems could be used to increase the efficiency of the CERN Large Hadron Collider (LHC) and the Future Circular Collider (FCC) as well as to reduce the very high power needs of a future Muon Collider (MC). The performance of SMES for other applications and late developments of the technique will also be described. LÄS MER

  5. 4. Quartic Higgs self-coupling at a 100 TeV pp collider

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Sebastian Grabowski; [2021]
    Nyckelord :Quartic Higgs self-coupling; Triple Higgs production; Future Circular Collider; FCC; MadGraph; MadAnalysis; Events selection; selection strategy; Physics and Astronomy;

    Sammanfattning : We present a parton-level phenomenological study of triple-Higgs production at leading order in proton-proton collisions at a center-of-mass energy of 100 TeV with an integrated luminosity of 30 ab^-1. This study aims to estimate the prospects for measuring the signal hhh production observable at the Future Circular Collider. LÄS MER

  7. 5. Towards Vertexing Studies of Heavy Neutral Leptons with the Future Circular Collider at CERN

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Rohini Sengupta; [2021]
    Nyckelord :Particle Physics; CERN; Future Circular Collider; FCC-ee; Heavy Neutral Leptons; Long-lived particles; Displaced signatures;

    Sammanfattning : Heavy Neutral Leptons (HNLs) are the heavier counterparts of the light neutrinos of the Standard Model of particle physics. HNLs can simultaneously solve several of the problems the Standard Model cannot yet resolve, one example being that they provide a candidate for Dark Matter. LÄS MER
