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

    University essay from Uppsala universitet/Högenergifysik

    Author : Magdalena Vande Voorde; [2023]
    Keywords : ;

    Abstract : 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. Studies of Dark Showers for Present and Future Colliders

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Nicoline Krogh Hemme; [2022]
    Keywords : high-energy particle physics; dark matter; collider physics; beyond the standard model; Physics and Astronomy;

    Abstract : In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. READ MORE

  4. 3. Towards Vertexing Studies of Heavy Neutral Leptons with the Future Circular Collider at CERN

    University essay from Uppsala universitet/Högenergifysik

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

    Abstract : 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. READ MORE

  5. 4. Long-Lived Particles at the FCC-ee

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Rohini Sengupta; [2021]
    Keywords : Particle Physics; CERN; Future Circular Collider; FCC-ee; Long-lived particles;

    Abstract : The presented project explores the current theoretical and experimental tools available within the study group for the Future Circular Collider (FCC) with focus on the electron-positron collider. The aim of the study is to evaluate the current frameworks used for simulation, and investigate the possibility of simulating long-lived particles, that could be dark matter candidates, through them.

  6. 5. Exotic Decays of a Vector-liketop Partner at the LHC

    University essay from Uppsala universitet/Högenergifysik

    Author : Alexander Skwarcan-Bidakowski; [2019]
    Keywords : Particle physics; Vector-like quarks; VLQ; Composite Higgs model; CHM; Top-partner; pseudo; Nambu-Goldstone boson; pNGB; NGB; ATLAS; LHC; CMS; Significance; Recast; CheckMate; CM; MadGraph; Pythia; Delphes; Detector; Analysis; Hierarchy Problem; Exotic; Decay; QFT; Quantum Field Theory; fermions; bosons; Jets; photons; leptons; 13 TeV; Missing Transverse Energy; momentum; hypothetical; selection criteria; Standard model; Signal; background; event; Higgs; Mechanism; Simulation; Confidence limit;

    Abstract : An evaluation of how sensitive some ATLAS searches for new physics are to a new beyond standard model (BSM) vector-like quark (VLQ) and a pseudo Nambu-Goldstone boson (pNGB) scalar. This was done by simulating a signal containing these new particles and making a recast of it onto existing verified ATLAS searches for new physics at center-of-mass (CM) energy of 13 TeV (Run 2) at the Large Hadron Collider (LHC).
