1. 1. The last unknown leading order low-energy constant of chiral perturbation theory

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Magnus Bertilsson; [2024]
   Nyckelord :QCD; Form factors; Vector form factors; Chiral perturbation theory; Hadrons; Hadron physics; hyperon decay; semileptonic decay;

   Sammanfattning : .... LÄS MER

3. 2. Defining dark jets at the particle level

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

   Författare :Gustav Lindberg; [2023]
   Nyckelord :Particle physics; Dark matter; QCD; Physics and Astronomy;

   Sammanfattning : One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. LÄS MER

4. 3. Probing Charm Production with Three-Particle Correlations in pp Collisions

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

   Författare :Kim Haupt; [2023]
   Nyckelord :pp collisions; charm production; three-particle correlation; Pythia; Physics and Astronomy;

   Sammanfattning : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. LÄS MER

5. 4. Neutron Veto Inefficiency Studies with FLUKA for the LDMX Hadronic Calorimeter

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

   Författare :Jaida Raffelsberger; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter".

7. 5. Studies of the axial-vector transition form factors of the process Ω− → W−Ξ0 in chiral perturbation theory

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Hélène De Munck; [2023]
   Nyckelord :Transition form Factors; Next-to-next-to-leading order; chiral perturbation theory; axial-vector; Ω− → W−Ξ0;

   Sammanfattning : This work is included in a broader research of the hadron theory group of Uppsala University and its collaborators tackling the quest for an understanding of the quark distribution inside hadrons by joining threedifferent approaches of QCD namely chiral perturbation theory, dispersion theory and lattice QCD. This thesis contributes by computing in chiral perturbation theory, the quark-masses dependence of form factors. LÄS MER
