1. 16. The Strong Potential of ΛΛ Femtoscopy at HADES

   University essay from Uppsala universitet/Kärnfysik

   Author : Malin Bohman; [2022]
   Keywords : hyperon; hyperons; Λ hyperon; ΛΛ; femtoscopy; correlation studies; strong interaction; hyperon interaction; hyperon interactions; HADES;

   Abstract : The aims of this thesis project have been to determine the feasibility of hyperon reconstruction utilizing a newly developed and implemented vertex fitter based on the Lagrange multiplier method. This was achieved through simulation and subsequent analysis of the reaction specified below, detailing the production of Λ-hyperon and K+ -meson pairs from proton-proton collisions. READ MORE

3. 17. Autoencoder Compression in High Energy Physics

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Author : Sten Åstrand; [2022]
   Keywords : High energy physics; LHC; ATLAS; hadron jet; machine learning; autoencoder; dimensionality reduction; artificial intelligence; data compression; Physics and Astronomy;

   Abstract : Situated in Geneva, Switzerland, the Large Hadron Collider is largest particle accelerator in the world, and as such, its operation carries with it some of the greatest technical challenges ever faced. Among them are the huge demands put on data storage capacity by experiments in particle physics, both in terms of rate and volume of data. READ MORE

4. 18. Projections for charm balance functions in heavy-ion collisions

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Tilde Bonnevier Wallstedt; [2022]
   Keywords : Heavy-ion physics; quark-gluon plasma; QGP; balance function; charm quark; Physics and Astronomy;

   Abstract : In this thesis, pp collisions were simulated using PYTHIA. D+ D- and D0 D0bar balance functions were created in order to contribute with a reference point for future balance functions measured in real data from Pb-Pb collisions. READ MORE

5. 19. Understanding Rt using two-particle correlations by simulating proton-proton collisions in a Monte-Carlo model

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Johan Leygonie; [2021]
   Keywords : QGP; Quark-Gluon-Plasma; Rt; Particle Physics; Proton-proton Collisions; Pythia; Monte-Carlo Model; Bachelor s Thesis; Heavy-ion Collisions; ALICE; CERN; Relative Transverse Activity; Jets; Two-Particles Correlations; Quantum Physics; Physics and Astronomy;

   Abstract : The observable Rt is investigated in the Monte Carlo Model Pythia in order to better understand results from experimental data obtained in the ALICE detector at CERN. The purpose is to reproduce the experiment in a simulation and use the features proposed by Pythia to dig into the unexpected outcomes. READ MORE

6. 20. Investigation of Autoencoders for Jet Images in Particle Physics

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Partikel- och kärnfysik

   Author : Jessica Lastow; [2021]
   Keywords : data compression; anomaly detection; jet image; autoencoder; dark matter; machine learning; ATLAS; hadron jet; particle physics; high energy physics; Physics and Astronomy;

   Abstract : Dark matter is an invisible type of matter believed to make up 85 % of the matter in the universe, but it has not yet been identified by experiments. According to certain particle physics theories, possible signatures of dark matter are so-called dark jets. They are the dark matter equivalent to classic jets, i.e collimated streams of particles.
