  1. 1. Non-Diffractive Nuclear Excitations In Angantyr

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Carl Rosenkvist; [2023]
    Nyckelord :Heavy-ion; non-diffractive; nuclear excitation; secondary interactions; Physics and Astronomy;

    Sammanfattning : To better understand collectivity in high energy physics, the heavy-ion collision model Angantyr was developed to be included in the event generator Pythia. In this model, proton-proton collision phenomenology is extrapolated to heavy-ion collisions without assuming a thermal plasma for particle production. LÄS MER

  3. 2. Non-perturbative models of diffractive hadronic collisions

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

    Författare :Edgars Karnickis; [2022]
    Nyckelord :diffractive process; proton-proton collision; elastic; parton; PDF; saturation; Physics and Astronomy;

    Sammanfattning : In this thesis, a new model for diffractive proton-proton collisions is presented. Interpreting protons as systems of many partons, we treat diffraction in terms of elastic interactions between the partons of the colliding protons. LÄS MER

  4. 3. Study of the doubly charged Higgs boson single production using lepton parton distribution functions with the ATLAS detector

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Daniel Magdalinski; [2022]
    Nyckelord :doubly charged Higgs boson; ATLAS; lepton parton distribution function; same-sign; dilepton; beyond standard model; LHC; Physics and Astronomy;

    Sammanfattning : Searches for the doubly charged Higgs(H±±) aim to find evidence for models that could explain the origin of neutrino masses. Earlier searches at the LHC have used different production processes for the H±±, with the recent development of lepton parton distribution functions new leptonic production processes are able to be studied.

  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. Di-Higgs Production in the Standard Model and Beyond

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Hanna Brännström; [2021]
    Nyckelord :ATLAS; CERN; Higgs; partikelfysik; di-Higgs;

    Sammanfattning : 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. LÄS MER
