1. 16. Probing Strangeness Production in Proton-Proton Collisions with Three-Particle Correlations

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

   Författare :Melinda Petricean; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Strangeness production in small systems such as proton-proton collisions is here investigated through the use of three-particle correlations in the momentum-space coordinates η and ϕ. This method is used in order to investigate possible correlation between conservation of both strangeness and baryon number, such that the particles chosen are Λ¯pK+ and the respective charge conjugates, where Λ is a strange baryon, p¯ balances: the Balance Function and the comparative restriction of relative positions for pairs of particles within given triplets.

3. 17. Trigger-Level Multiple Electron Event Classification with LDMX using Artificial Neural Networks

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

   Författare :Jacob Lindahl; [2023]
   Nyckelord :LDMX; ANN; CNN; GNN; RNN; DM; Physics and Astronomy;

   Sammanfattning : Artificial neural networks is a powerful tool for classifying and identifying patterns in large amounts of data. One of the possible tasks of these networks is classification of data into categories. LÄS MER

4. 18. Time-dependent light-matter coupling and quantum dynamics

   Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Daniel Elgbro; [2023]
   Nyckelord :light-matter interaction; Rabi oscillations; quantum dynamics; optical cavity; qubit; coupled qubit; coupling strength; time-dependent coupling; dynamical qubits; entanglement; concurrence; qubit state manipulation; Jaynes-Cummings; Tavis-Cummings; Physics and Astronomy;

   Sammanfattning : In this thesis, two quantum dynamical system’s of one and two qubits coupled to a field mode confined in an optical cavity have been studied. Within the Jaynes- and Tavis- Cummings model, the dynamics of the corresponding light-matter interaction was defined in terms of the system’s coupling constants. LÄS MER

5. 19. Validation of simulation with enhanced kaon production to investigate kaon background for LDMX

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

   Författare :Lisa Andersson Loman; [2023]
   Nyckelord :Dark matter; experimental physics; simulations; kaons; particle physics; LDMX; background studies; mörk materia; partikelfysik; kaoner; Physics and Astronomy;

   Sammanfattning : Dark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. LÄS MER

7. 20. Studies of the J/Ψ → anti-Σ0Σ0 Reaction with BESIII : Event Selection Development

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Benjamin Verbeek; [2023]
   Nyckelord :hyperon; CP; symmetry; event selection; tracks; BES; BESIII; USTC;

   Sammanfattning : The apparent symmetry between matter and antimatter raises the question of why the universe consists of mostly matter. Via an academic exchange to USTC Hefei, a reaction was studied that aims to give insight into this question. LÄS MER
