  1. 1. Pulse Amplitude Reconstruction in the LDMX Hadronic Calorimeter Readout

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

    Författare :Aksel Draguanov Mihaylov; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The universe shows signs of containing some invisible matter, known as dark matter. There are many possible constituents for dark matter, one such being light dark matter which would interact with ordinary matter through a new mediator force and have masses in the range of a few MeV to GeV.

  3. 2. 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. 3. Assessment of the Capability for Vetoing Beta-Decay Events in the Lundium Decay Station

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Tanvir Sayed; [2022]
    Nyckelord :Radioactivity; Decays; Radiation; Ionisation; Superheavies; Exotic isotopes; Decay spectroscopy; Semiconductors; Silicon-Strip Detectors; Lundium; Vetoing; Electron spread; Particle identification; Physics and Astronomy;

    Sammanfattning : Alpha decay spectroscopy using the latest and most sensitive detector setup as well as fast sampling read-out electronics has become very important for discovery and analysis of short-lived nuclei created in collision experiments in the laboratory. The Nuclear Structure Group in Lund is currently developing the Lundium Decay Station for use in comprehensive nuclear spectroscopy of decays for rare isotopes, particularly in the heavy & superheavy region.

  5. 4. Exploring a Two Higgs Doublet Model with a U(1) Family Symmetry and a Complex Singlet

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Michal Nowak; [2021]
    Nyckelord :Two Higgs Doublet Model; Complex Singlet Extension; Phenomenology; Physics Beyond the Standard Model; Branco-Grimus-Lavoura Model; Physics and Astronomy;

    Sammanfattning : In this project a two Higgs doublet model with a complex singlet and an extra family symmetry providing a mechanism for suppression of flavor changing neutral currents is explored. The goal is to investigate the phenomenological consistency of the model using a custom software framework. LÄS MER

  7. 5. "Budapest in Warzaw" eller en polsk palatsrevolution? : en fallstudie om avdemokratisering i Polen

    Kandidat-uppsats, Försvarshögskolan

    Författare :Amalia Holm Bjelke; [2019]
    Nyckelord :de-democratization; Poland; palace revolution; democracy; Merkel; European Union; democratic peace; hybridization; defect democracy; avdemokratisering; Polen; palatsrevolution; demokrati; demokratiindex; Europeiska Unionen; demokratisk fred;

    Sammanfattning : Taking off from a security related interest in de-democratization processes throughout Europe and the limited theoretical field thereof, this paper examines the political development in Poland 2008-2018. Through a comparison of the development in Poland and Hungary, the ambition is to identify what differs the de-democratization process of the two East European countries in regards to their communist past and in a broader sense to their current membership in the European Union.
