  1. 16. Quartic Higgs self-coupling at a 100 TeV pp collider

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Abstract : 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. READ MORE

  3. 17. Di-Higgs Production in the Standard Model and Beyond

    University essay from Stockholms universitet/Fysikum

    Author : Hanna Brännström; [2021]
    Keywords : ATLAS; CERN; Higgs; partikelfysik; di-Higgs;

    Abstract : This thesis examines how the kinetic properties of pair-produced Higgs bosons depend on whether the process is mediated by particles in the Standard Model or a simplified supersymmetric model. The analysis is based on simulated data made using MadGraph. READ MORE

  4. 18. A literature review of FASERν - An emulsion detector for collider neutrinos

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

    Author : Lisa Andersson Loman; [2021]
    Keywords : physics; neutrinos; FASER; Standard Model; Beyond Standard Model; BSM; particles; elementary particles; neutrino cross sections; LHC; FASER nu; particle physics; physics experiment; CERN; long lived particles; Physics and Astronomy;

    Abstract : In 2021, the ForwArd Search ExpeRiment (FASER) will start searching for light and weakly coupled particles 480m from the proton-proton collision point of ATLAS at the Large Hadron Collider (LHC). The FASER main detector will have a sub-detector, FASERν, sensitive to high-energy collider neutrinos of all flavours. READ MORE

  5. 19. Radiative Corrections Beyond the Soft-Photon Approximation

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Jacob Lindahl; [2021]
    Keywords : Soft-Photon Approximation; Bremsstrahlung Correction; Transition Form Factor; Radiative Corrections; Physics and Astronomy;

    Abstract : This thesis calculates the bremsstrahlung correction beyond the soft-photon approximation for the decay ω → π0 l+ l- . The effect of the radiative corrections on the extraction of the transition form factor from data is investigated. READ MORE

  6. 20. Resolving Quasi-Degenerate Higgs Bosons

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Gustav Lindberg; [2021]
    Keywords : Particle physics; Higgs boson; Beyond the Standard Model; Physics and Astronomy;

    Abstract : Many models beyond the Standard Model that predict the existence of multiple Higgs bosons. In general, some of these additional Higgs bosons could be quasi-degenerate in mass either to each other or to the observed 125 GeV Higgs boson. The goal of this thesis is to study under which circumstances we can resolve such Higgs bosons. READ MORE
