1. 21. 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

3. 22. 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

4. 23. 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. 24. Search for Higgs-like bosons through optimization of top-quark modelling

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

   Author : Rafael Antonio Lopez; [2021]
   Keywords : ttbar; top quark modelling; BSM; 2HDM S; Higgs-like bosons; ATLAS; HWW; XSh; top estimation; top remodelling; Physics and Astronomy;

   Abstract : Accurate estimations of background processes associated with top-quarks are vital to studies concerned with finding new physics at the Large Hadron Collider (LHC)at CERN. Search for Higgs-like bosons in the ATLAS experiment at LHC was performed by optimising the use of b-jet tagging algorithms and improving on tt backgroundmodelling. READ MORE

6. 25. Impact of different primary particles on Geant4 simulation execution time - study on protons and pions

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

   Author : Rebecca Jigström Madeira; [2021]
   Keywords : Geant4; Monte Carlo method; Large Hadron Collider; simulation time; collider experiment; Physics and Astronomy;

   Abstract : The High Luminosity Large Hadron Collider (HL-LHC) at CERN, an improvement to the LHC, scheduled to be operating in 2027, will further the potential for scientific breakthroughs in High Energy Physics. The project’s demand in computational resources, however, is predicted to exceed what will be available then. READ MORE
