  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. Explaining B-> D^(*) tau nu Decays with a Two Higgs Doublet Model using the Froggatt-Nielsen Framework

    Kandidat-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Emil Andersson; [2017]
    Nyckelord :Two Higgs Doublet Model; 2HDM; Froggatt-Nielsen; Flavon; B-meson; Higgs; Beyond Standard Model; BSM; Theoretical Particle Physics; Physics and Astronomy;

    Sammanfattning : In recent years, the BaBar, Belle and LHCb experiments have observed an excess of $B\to D^{(*)}\tau\nu$ decays compared to Standard Model predictions. In this thesis, we investigate if it is possible to explain this excess with a two Higgs doublet model using the Froggatt-Nielsen framework. LÄS MER

  4. 3. Tekniker för detektion av neutriner med ultrahög energi

    Kandidat-uppsats,

    Författare :Lawen Ahmedi; Mubarak Ali; Larisa Castellanos; [2017]
    Nyckelord :Teknik; tekniker; detektion; detektera; detektorer; detektor; observator; elementarpartikel; neutrino; neutriner; ultrahög; energi; fysik; astronomi; astrofysik; kosmisk strålning; radiostrålning; radiostrålar; partikel; partiklar;

    Sammanfattning : This project highlights various methods used to detect the elongated elemental particle neutrino. It is especially focused on the IceCube observatory, which uses Cherenkov light to detect these particles. LÄS MER

  5. 4. A Search for Indications of Majorana Neutrinos in Same-sign Dimuon Events at the ATLAS Detector

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

    Författare :Simon Arnling Bååth; [2014]
    Nyckelord :Majorana Neutrino; ATLAS; Dimuon; Neutrino; LRSM; Physics and Astronomy;

    Sammanfattning : Abstract The current Standard Model cannot explain many properties of the neutrino, including its mass. Models exist where a postulated heavy Majorana neutrino will give rise to the observed small neutrino mass currently observed. LÄS MER
