1. 6. Mono-X signal characterisation from two-component DarkMatter using Neural Networks

   University essay from Uppsala universitet/Högenergifysik

   Author : Max Fusté Costa; [2023]
   Keywords : ;

   Abstract : In the recent decade, neural networks have become one of the leading tools in the search for the elusive nature of dark matter and its interactions through the analysis of numerically simulated data. This project introduces a minimal dark sector consisting of three additional fields and studies it through two mono-X signatures,mono-jet and mono-Z. READ MORE

3. 7. Neutron backgrounds in neutrino-nucleus scattering at the European Spallation Source

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

   Author : José Guilherme Rodrigues de Albuquerque Vale; [2023]
   Keywords : Neutrino-nucleus scattering; background; PHITS; weight window; ESS; Physics and Astronomy;

   Abstract : Being, when built, the most powerful neutron accelerator in the world, there will be a large number of potential discoveries at the European Spallation Source (ESS) in Lund. One of the most exciting of these, from a particle physics point of view, is the Coherent Elastic Neutrino-Nucleus Scattering (CEνNS). READ MORE

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

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

   Author : Jaida Raffelsberger; [2023]
   Keywords : Physics and Astronomy;

   Abstract : 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".

5. 9. Dark Matter signals at the Large Hadron Collider with Deep Learning

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Max Andersson; Edward Glöckner; Carl Löfkvist; [2023]
   Keywords : Machine Learning; Dark Matter; Classification; Regression; Particle Physics; Supersymmetry; LHC; CERN;

   Abstract : While holding a firm position in popular culture and science fiction, Dark Matter (DM) is nonetheless a highly relevant topic at the forefront of modern particle physics. We study the applicability of characterizing DM particle candidates SUSY neutralino and sneutrino using Deep Learning (DL) methods. READ MORE

6. 10. The Higgs Width in Higgs production in association with a W+ boson

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Wijeratne Mohandiramge Umashi Navisha Fernando; [2023]
   Keywords : Higgs boson; Higgs width; off-shell; on-shell; narrow-width approximation; MadGraph5_MC@NLO; W boson; supersymmetry; dark matter; Physics and Astronomy;

   Abstract : The width of the Higgs boson is a quantity that cannot be measured directly from the on-shell Higgs peak; it would have to be measured indirectly. In 2013, Caola and Melnikov developed a method to determine the Higgs width by using off-shell and on-shell cross-sections and applying the narrow-width approximation. READ MORE
