  1. 1. Long-Lived Particles from exotic Higgs decays at the FCC-ee

    University essay from Uppsala universitet/Högenergifysik

    Author : Magdalena Vande Voorde; [2023]
    Keywords : ;

    Abstract : This thesis presents the first sensitivity analysis for exotic Higgs boson decays at the electron-positron stage of the Future Circular Collider (FCC-ee) within the FCCAnalyses framework. The project studies the production of a Higgs boson in association with a Z boson in electron-positron collisions at a center-of-mass energy of 240 GeV, with the Higgs boson decaying into two long-lived scalars and the Z boson decaying leptonically.

  3. 2. 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. 3. Optimization of event selection and fake background estimation in a search for heavy scalars in dilepton final states with the ATLAS detector

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

    Author : Marius Burman Ingeberg; [2021]
    Keywords : Physics; Particle physics; ATLAS; Standard Model; CERN; LHC; Higgs boson; Exotic Higgs Boson; Dilepton final states; Optimization; Physics and Astronomy;

    Abstract : The discovery of the Higgs boson h in 2012 further confirmed the remarkable accuracy of the Standard Model (SM). Despite this, some compelling excesses in multi-lepton final states were recorded in both major runs of the Large Hadron Collider (LHC). READ MORE

  5. 4. Study of Kinematic Variables in Multi-Lepton Final States in search for an Exotic Higgs Boson

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

    Author : Axel Gallén; [2021]
    Keywords : LHC; ATLAS; CERN; Standard Model; Higgs boson; Exotic Higgs boson; Kinematic variables; Physics and Astronomy;

    Abstract : The Large Hadron Collider in Geneva was constructed as a discovery machine. So far, the Higgs boson has been the only discovery at the Large Hadron Collider, but physicists keep on pushing the limit in order to discover new particles. READ MORE

  6. 5. Exotic Decays of a Vector-liketop Partner at the LHC

    Abstract : An evaluation of how sensitive some ATLAS searches for new physics are to a new beyond standard model (BSM) vector-like quark (VLQ) and a pseudo Nambu-Goldstone boson (pNGB) scalar. This was done by simulating a signal containing these new particles and making a recast of it onto existing verified ATLAS searches for new physics at center-of-mass (CM) energy of 13 TeV (Run 2) at the Large Hadron Collider (LHC).
