  1. 1. Non-Diffractive Nuclear Excitations In Angantyr

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

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

    Abstract : 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. READ MORE

  3. 2. Signatures of Dark Matter at the LHC : A phenomenological study combining collider and cosmological bounds to constrain a vector dark matter particle model

    University essay from Uppsala universitet/Högenergifysik

    Author : Anton Olsson; [2022]
    Keywords : Dark matter; particle phenomenology; LHC; MadGraph; standard model; beyond standard model;

    Abstract : Everything that humans have ever touched, created or built something from consists of a type of matter that only makes up 15 percent of the total matter in the universe. The remaining 85 percent is attributed to dark matter, a so far not discovered and non-luminous type of matter. READ MORE

  4. 3. 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

  5. 4. Phenomenology of a Three Higgs Doublet Model with a U(1)xZ2 flavour symmetry

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Ian Padilla; [2019]
    Keywords : Phenomenology Physics Beyond the Standard Model Three Higgs Doublet Model Flavour Symmetry; Physics and Astronomy;

    Abstract : We have studied the main features and the phenomenological consistency of a family-nonuniversal Three Higgs Doublet Model (3HDM) with a softly broken U(1)xZ2 family symmetry that enforces the flavour hierarchies in the Standard Model (SM) while implementing a tree-level Flavour Changing Neutral Current (FCNC) suppression in a Branco-Grimus-Lavoura way. Furthermore, the alignment limit is imposed in the scalar sector to enforce the physical scalar spectrum to accommodate a SM-like Higgs boson. READ MORE

  6. 5. Studies of the Phenomenology of H+ → W+Z events with ATLAS at LHC

    University essay from Högenergifysik

    Author : Henrike Fleischhack; [2012]
    Keywords : High energy physics; particle physics; Higgs boson; charged Higgs boson; LHC; ATLAS;

    Abstract : The Higgs sector is the last part of the standard model of particle physics where we lack directexperimental results. Many extensions to the standard model describe an extended Higgs sector,often containing charged scalar bosons in addition to the standard model’s neutral Higgs boson. READ MORE
